Changing Pricing Based on Form Selections

My form has fields for purchasers to tell me how long they do an activity each day and then has tiered pricing based on the number of hours of activity they do each week. Right now I have the purchaser complete the daily activity fields and then choose the pricing option that matches to their weekly hours (so they have to do the calculation themselves). Is there a way to instead attach values to the daily activity fields, which would then calculate the weekly amount, and put the purchaser into the correct pricing tier automatically?

Example: Purchaser chooses Monday: 1hr (value = 1), Tuesday: 30min (value = 0.5), Wednesday 90min (value = 1.5), Thursday 2hrs (value = 2), Nothing Friday, Saturday, Sunday, This would calculate to 5 and would put the purchaser in the pricing tier of 5-7.

Thanks!

Interesting, that would be fantastic. The form is at http://www.getfitpack.com/join-fitpack.

Right on man, glad to see you are getting this going! So instead of using the "admin only", you might want to resort to hiding the field with CSS via display:none. You can inspect the field via chrome dev tools or firebug for firefox and ID the field (each field has it's own unique ID). You could also create a class as well to add to each field, if there are multiples and target that class to hide them.

Actually, you can use the gf_hidden class and apply that to your field that you want hidden (it will be in the Advanced Tab of the field editor). Then you won't have to worry about adding any custom CSS. Sorry I didn't think of that before, but that will be much easier. :)
