populate field with value field of previous page

Hi,
In my form (to register the kilometres a car has driven on weekdays) I want to reuse the value that's entered in a number field on page 2 (monday) to be populated to a number field in page 3 (tuesday) (page 1 contains general information about the driver).

The value the car has ended with on monday must be the populated starting kiliometres for tuesday and so on for the rest of the week.

1.
I have been reading several topics on this forum and thought I was nearby a solution with this http://www.gravityhelp.com/forums/topic/populate-field-from-previous-field

but I can't seem to understand the last part of the code mentioned:

// update this to the ID of the field whose value you wish to call
// '16.3' = example, first name of a Name field
// '16.6' = example, last name of a Name field
$field['defaultValue'] = rgpost('input_16_3');

in my form (i can't send a URL because of security) I have form id = 5, field that should be populated id=87 and field that contains the value i want to reuse=9

I also wonder if I need to change anything on the pagenumbering in my case (monday is page 2, tuesday is page 3).

Then last but not least. If I use this code, my pre-populated field with the user_name displayed is changed to empty...

2.
Since the field is a number field I already have been thinking of a workaround since the field value I want to be populated is in a number field I could use the new calculation function on page 3 (just saying: use field 9 + zero). That works basically like expected, but the problem I face there is the thousand seperator that is bothering me. People filling out this form won't type their kilometres with a thousand seperator...

Hope somebody can help me out on either one of these two 'solutions'.

Thanks,
Jolanda

Can you use pastie.org to show me your PHP function code you are using/have placed?

If I use this code in functions.php http://pastie.org/4230595 the problem is like described under 1.

I now just found out, that for the workaround mentioned above under 2. the problem is that the thousand seperator is used as a decimal seperator.

for example monday starting on 10400 and ending on 10500 gives starting on tuesday 10.500 When used further on in the calculation this is been seen as 10,5 instead of 10 thousand 500. So probably this is the real problem in my case...? In the field, the format is set to 9.999,99

I now changed the calculation by adding *1000 to it and it now seems to work....!!

But I am still curious why this code http://pastie.org/4230595 isn't working like expected.

Also these may be of some interest. I can get neither to work so if any admins are reading this and want to help please jump in!

Field ID's being used - Take contents from field ID 18 and put it into field ID 24 on a 4 page form, form ID = 1 (note in the source code field 18 seems to have an ID of tos-18)

My Code: http://pastie.org/4230723

This one also came from the GForms forums http://pastie.org/4230744 and uses JQuery.

Both of these seem to make perfect sense and work as I would have expected this to work but for some reason don't! This is getting really annoying so fingers crossed we can get somewhere.

Also forgive me if I've missed the point slightly but could you not convert the numerical field to a string, use string manipulation to format it correctly and then pass it to the process afterwards, so GForms will treat it as a string so you can use input masks and validation to format it correctly and then convert it to a number for work behind the scenes?

After experimenting some more that last pastie I posted will work on the same page wonderfully cause I've used it to fill some hidden post fields from some of the more advanced fields such as the address field.

However, I've manage to get one bit of code to pass a value between page one and two here:

http://pastie.org/4245987

This has been outlined somewhere else on the GForms forums but I can't find it so I'm reposting mine but IT IS NOT MY WORK. Ok so that's clear, I've posted a bit to much here, it's the complete set of functions to build a user ID out of a post code entry and then modifying the string and returning it to a field on the next page. I included it all to allow anyone unsure to pick through it and understand and make sure there's nothing left to doubt about odd function calls. With this I've managed to get it to post the same thing in multiple fields by giving the output a second if statement and CSS name but I haven't been able to apply it to another setup for some reason.

I'm sorry if that's a bit wordy but I just want to avoid doing what I've seen on here and assuming people get things when they may not, I rarely do lol. Once again it's not my work but I've commented it as I've figured it out, hope this helps elizabethanne.

I got it to work but as I said only between fields on the same page. The way it works to the best of my understanding is when you click into the field you want to populate from it loads the script and then when you click elsewhere it fires the populate function.

But this will only work between two forms on the same page NOT between pages. If it's not working for you the only thing I can think of is that perhaps you haven't got JQuery active in your theme, that was a problem I had to start with.

But as I said in my previous post http://pastie.org/4245987 is the only script I've manage to get to pass field data between pages I'm afraid.

PS - Sorry about the delay I'm in GMT time zone so it was late :-)
