What does that other embed code do?

I have the same issue. I was able to embed just the iframe portion of the code it did resolve my problem.  My question is what does that other part of the code do?  Is there any less functionality in the form now that I've stripped down the code?

Thanks

Are you referring to the script code below the iFrame?

The purposes of that script code is to automatically resize the form depending on the size of the actual form. However, we normally suggest to remove it if there are any script conflicts.

No, your form will still work properly. Removing the script code will not affect the functionality of the form since this is just an embed code.

Let us know if you have any questions. We'll be glad to assist you.
