I want to add a custom variable to a free button. The problem is that I want to populate the variable with the contant of a dynamic cascade field.
The link I desire is something like this: www.mysite.com/form.html?varname=[value]&...[other parameters]
I try to fill the value in fields->form_settings (you can see the screenshots)
identifing the value of the field using the syntax #dynamicfieldname#, or @dynamicfieldname, but doesn't work.
Setting a static value in the get parameter of the url it passes.
Someone can help me? thank you
