Can't get submit button to work

I tried the iFrame method on my Wordpress.com site. It will just show the coding. If I use the Embed via 3rd Party Method using Wordpress.com as the selection, the form will appear, but the submit will not proceed past "Please Wait".

At the moment, I have to use a custom URL redirect, and have my clients access the form directly. 

Is there a better fix for this than a workaround?

The screenshot attached is if I remove the URL redirect.

You should add the iFrame code in your WordPress post/page as “Text”.

You can also check this guide:

A Guide to Embed Forms for WordPress Users

That's how the iFrame code was input on my Wordpress, was as "text" via the Text Block.

I still get the result I originally posted unfortunately.

Please try with the script code, by following the steps from this guide:

How to Embed a Form to Wordpress.com 

Using that method is why I wrote into the forums to begin with.

"If I use the Embed via 3rd Party Method using Wordpress.com as the selection, the form will appear, but the submit will not proceed past "Please Wait". "

Doesn't seem there's an answer to this issue other than the URL redirect. That's fine.

Thanks for your time.

This should now be fixed.  Apologies.  Please let us know if this conditions or submit functionality are still not working on your end and we will take a look immediately.
