OK,
i tested it and it works.
Let me explain what i did:
In your 1.0.3, add the sample form to start, then Add a new field like this:
Field Id: radioselect
Field type: radio
Default value: paypal.html|Paypal,moneybookers.html|Moneybookers,cc.html|Credit Card
Field style:
| Code: |
<tr>
<td>{fieldtitle}</td>
<td align="right" valign="top" colspan="2">{field}</td>
</tr>
|
(i altered the main field style, by removing the third cell, so the radios can expand).
Then, in your Edit Form screen, under the Form Edit tab, add this:
Return URL : {radioselect}
This way, when someone selects Paypal, the data is stored, and they are being redirected to paypal.html and so on.
Let me know if it worked.
