Submitting data from single tab using multiple tab form

[Orion709]

I have a flash form with multiple tabs. When a submit button is pressed,
however, I would like only the information from the current tab to go to the
server.

I have tried disabling the fields on the non-selected tabs...
if (tabs.selectedIndex == 0)
{document.dateOrdered.enabled = false; ... }

and disabling the entire non-selected tabs
if (tabs.selectedIndex == 0)
{ tabs[1].enabled = false; ... }

This will indeed disable the field or tab on the form, but when the form is
submitted and I dump the form variables,
i.e.
<cfif IsDefined("form.fieldnames")>
<cfdump var="#form#">
</cfif>

they all still show up. Am I expecting the wrong results, or just going
about this the wrong way?

Thanks for any advice you can offer.
