Salesforce integration with google analytics requires a simple hidden field in the source:
<INPUT type="hidden" name="sfga" value="insert-your-salesforce-oid-here"/>
I've added the required hidden field, but the form still fails the sfga test. It doesn't look like gravity forms displays the hidden fields, instead they are passed through during post, or am I missing something? Can I get a hidden field in the gravity form some other way?
