Sorry, i didn’t know how formulate that so i will explain
I want 2 steps
One ==> Create short form with payment (normally is ok)
Two ===> To have a second form that is more comprehensive and includes additional fields, with the fields pre-filled with the customer’s values from the first form.
This should be possible with our Gravity Forms Easy Passthrough. You can set up form two to receive the entry data submitted in form one and map the values to their respective fields. Here’s a tutorial documentation with a similar setup. Check it out and let us know if you have any questions.
