I finished another set of forms that I am trying to use with a 'CSS Tabs' module; module is installed on one page and displayed on another.

The form displays perfectly, save the formatting issues I am trying to work through without adding blank modules to each side to constrain it, except that the required fields are displaying an "Invalid URL" error with an * on the top of the forms where the errors display.

Is this not doable, or is there a setting I missed? I thought I checked something to pass the variables to another module, but not sure this is related.

Any suggestions?

Hmmmm... Odd, I am not familiar with integration directly with the CSS Tabs module but this sounds like a javascript error with client validation.

What is 'probably' happening is that the CSS Tabs needs to be se to 'CausesValidation=False'. This is because its probably trying to validation the form because it goes to the next page, is it possible one of your fields 'required field text' is set to 'Invalid URL'? Also, what happens when you uncheck 'Enable client side validation' within general settings? Does it work then? I could be completely off base here but thats what it sounds like to me so far.
