//	This script is for the No. Golfers select bug on 
//	the 3rd page of the price quote form.
//	basically pear isn't setting defaults to the elements
//	in the element grid if its within a controller page (multipage form controller)
//	What this script does is check if all the select boxes have the same index
//	ie. (they're all the same)  If they are, then it sets their default state to
//	the highest # of golfers available.  If they are not all the same
//	then that means the user has submitted this form once and changed the #
//	of golfers on one day and has since returned to this form to correct something
//	or is passing through to get to a previous or later form page.
