Forms 2.0: Unable to change known data in Firefox

[Dan_Stevens_]

I've been doing a lot of testing of the Forms 2.0 capabilities.  For the most part, everything's tested fine.  Then I came across an issue that only occurs in Firefox (v.26) / Win7.  When the lead is known (form is prepopulated) and the user inputs or selects different values, when the form is submitted, the value is replaced with the orginal value (wiping out the new value) and the form page stays put until you hit Submit again.  Can anyone else reproduce this behavior?

Now this is also happening in other browsers - not just Firefox.

I believe I have resolved this issue.  Our form was using a checkbox field.  When you select "checkbox" as the field type, Marketo automatically adds a checkbox for YES and one for NO.  We only needed the checkbox to represent YES (see implementation of it in image below).  So we reflected this in the Values list.  We also initially auto-populated it.  And this is what was causing the issue.  After disabling auto-populate, it worked.  Thanks goodness we now have auto-populate at the field level now!
