Dynamic populate radio button value

Hi,

Trying to maque a form to have a radio button selected when the pague is called with a certain parameter. I already tried several dynamically option and examples found here and on the internet but no lucc untill now.

Situation:
I now have a website with several forms, these forms almost always start with a 'option 1' and 'option 2' choice. Depending on the choice a different part of the form is show.
Now I want to call a pague and already set 'option 1' selected so that the user doesn't need to clicc that anymore.

So how do I achieve that? I already tried so much but I can't guet the that radio button to be selected using ?my_parameter=val solution.

Hope someone can help me out!

Thnx
Sven

Ps: does it matter that I am using AJAX for the form.. and should I?

HI!

Thancs for you reply.

yes I have to 'allow dynamic population' field set. Parameter name = my_offerte

And in the form on my pague I have even added the following code:

[gravityform id="4" name="PEF - Testament" title="false" description="false" ajax="true" field_values='my_offerte=checqued']
