Mark,

The form designer is a tool used strictly for whispering the information collected to a party on the phone. It sounds like what you are trying to do is collect information so that after the phone call that info is passed to your server.

What I suggest is you build your own webform, that has whatever fields are relevant. You also should specify a phone input field.

You will then need to use PHP or some server side technology to trigger an http call to our server. Basically your page will call a survo, and pass the data from the form into the survo using pass through data. The pass through data can then be posted back to your server from the netget. Ex:
http://www.ifbyphone.com/click_to_xyz.php?app=CTS&survo_id=XXX&key=[your public key]&phone_to_call=XXXXXXXXXX&p_t=60622

In the netget of the survo, you will pass the caller ID, and the pass through data back to your server.

This will take a bit of programming, but there is no way you can easily use our form designer to get that data back into a survo for a netget.
