Dynamic Field Population: Pass phone data to another phone field in same form

Hi guys,

I've read a whole bunch of posts on dynamic field population but they seem to be more complicated than what I'm after. I'm also not that familiar with php, javascript or jquery (just html and css) so I'm getting a little confused.

Gravity forms version:
1.5rc4 - multi-page form

What I need to do:
I would like to pass the phone number the user enters on page 1 of a multi-page form to another phone number field on page 4 of the same form.
On page 4 the user selects how they would like to be contacted and if they choose phone I'd like the phone number field to appear (I know how to do that part) pre-populated with the number they entered in page 1. I'd also like this same behaviour if they select email.

Link to the form:

Thanks guys!

Hi Carl. That would be great if you could provide me with a consultant. I'll probably leave it for a later release but I'll definitely need it at some point.
Thanks,
Elise
