Hi,
I’m glad you like DFFS!
You have misunderstood this functionality a bit as the built in functionality is used if you want to use the URL parameter as a trigger for a DFFS rule.
What you try to do can easily be done with a line of code in the Custom JS textarea.
First change your “heading” like this:
<p>Form Type: <span id='formTypePlaceholder'></span></p>
Then add this to the Custom JS textarea:
$("#formTypePlaceholder").html(GetUrlKeyValue("frmtype"));
