HTML Pane doesn't work all the time

I am working on creating a custom login form. I have the custom login form working https://webmail.swisher.com. There is an extra submit button in the code when you view the source, but the code is not anything I’ve placed there. I want to create a new CustomLoginForm, but when I do, the HTML pane selection is greyed out. My HTML code is created by a Web developer on staff and he can’t figure out where the Submit button at the bottom of the page is coming from either. What am I doing wrong and how can I fix these problems? Any help would be great. Thanks.

PS

I am in no way a developer, I can feel my way around Designer though.

I’m not sure why your HTML pane is greyed out, but there is an explanation for the Submit button. If, in your database properties, you have Use JavaScript when Generating Pages unchecked, a default Submit button is generated for all pages. You can hide it if you have your own submit button, or just check the Use Javascript property, and it will go away.

If you don’t have a Notes button, notes provides one, so put a notes button
between HTML hides !–Button–>]

Can you set form to be HTML form? If you do that, Notes won’t create the Submit button.

I have a vague memory that setting database to use Javascript for pages stops it as well, not sure.

Otherwise its the old old hack, of putting a submit button inside an HTML comment. iirc that has a problem as well in that if user hits enter, the hidden button is still activated.
