I have a page with 3 versions of a product (diff prices) each with its own 'Buy now' button.
I have only one Paypal Gravity order form with a PRODUCT field of 3 radio buttons i.e. 1 for each version. I want to auto select the correct radio button based on which 'Buy Now' Button is used. I have read how to dynamically populate a field but sadly do not know enough to succeed.
In gravity form the PRODUCT field is set to be populated dynamically with a parameter name VERSION. I can see the 3 radio button choices are:
My Buy Now variables are: ver1, ver2 and ver3.
If ver1 is select on the page then I want to select the 'gchoice_17_0' radio button
1) What do I put in the Buy Now button link to add variable eg ver1
2) Where & how in gravity form do I make the necessary connections
Any help will be greatly appreciated.
