Stuck at Please Wait when editor added

I have a form that sends to a recordset that works fine. But when I add the HTML editor to the textarea of the Comments field, it stays stuck at Please Wait with the circle thing.

All I did was select the form element, insert the editor, and upload the file. I don't think there are any other supporting files I need to upload to the server as I did this process with a similar form and it worked fine. The major difference between the two is the other form also uploaded its attachment on the server and inserted the name into a database. This one just sends the attachment to everyone, but it's not archived.

If I overwrite the html editor version with a non-html editor version, it works fine. As soon as I add the editor, it doesn't. The other files I've done this with all work. I've attached it if it helps.

Any help would be appreciated. Thank you.
