How to declare variable and call it later using text inputs...PLEASE HELP!

Hi there

I am pulling my hair out. I have a form with 3 input fields: Name, Email Address, and Contact Number. These have the following instance names: iFullname, iEmail, iContact

When the user clicks submit, I need to store this data and then call it later into another form. There are 3 input fields with the same instance names as the first form.

This form is in an external movie loaded into the main movie where the original data was stored.

Please could someone guide me as this is super urgent.

Regards
Levon
