OK my Bad! In "Administer>>Site Configuration>>Location" I should have unchecked the "Use a Google Map to set latitude and longitude" option since I dont' have a "Google map API key" to put in the GMAP module configuration. Now the Submit form works and the collapsible fieldsets work fine as well. One more this though, I want to change the field lengths of the location fields, how do I do that. I tried to use compact forms module but it's not helping, any suggestions?
