jqery ui datepicker :- passing variables

Having problems with two datepickers one of which the year dropdown caries the year from the other as it's minimum for year dropdown value.

The following code is executed, the onclose functions are called successfully but the global variable "ch_from_year" is not being altered by the onclose function although it is being used successfully within that function (i.e. it sets the right date for that datepicker but it does not seem to carry the value to the gloabal variable.)
var ch_from_year = '1940';
$(function() {
	$('#ch_from_date').datepicker({
		showOn: 'button',
		buttonImage: '../css/images/calendar.gif',
		buttonImageOnly: true,
		changeMonth: true,
		changeYear: true,
		minDate: new Date(1929, 1 - 1, 1),
		beforeShowDay: hideDays,
	 	yearRange: '1929:2010',
	 		dateFormat: 'mm-yy',
	        onClose: function(dateText, inst) { 
	            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
	            ch_from_year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
	            $(this).datepicker('setDate', new Date(ch_from_year, month, 1));
	        		        }
    	 	
	});
	
	});

$(function() {
	$('#ch_to_date').datepicker({
		showOn: 'button',
		buttonImage: '../css/images/calendar.gif',
		buttonImageOnly: true,
		changeMonth: true,
		changeYear: true,
		minDate: new Date(ch_from_year, 1 - 1, 1),
		beforeShowDay: hideDays,
	 	yearRange: '1929:2010',
	 		dateFormat: 'mm-yy',
	        onClose: function(dateText, inst) { 
	            var to_month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
	            var to_year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
	            $(this).datepicker('setDate', new Date(to_year, to_month, 1));
	        }
			 	
	});

	});

Hi  bjh497
I found two problems and i updated your code above:
var ch_from_year = '1940';
$(function() {
	$('#ch_from_date').datepicker({
		showOn: 'button',
		buttonImage: '../css/images/calendar.gif',
		buttonImageOnly: true,
		changeMonth: true,
		changeYear: true,
		minDate: new Date(1929, 1 - 1, 1),
		beforeShowDay: hideDays,
	 	yearRange: '1929:2010',
	 		dateFormat: 'mm-yy',
	        onClose: function(dateText, inst) { 
	            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
	            window.ch_from_year = $("#ui-datepicker-div .ui-datepicker-year :selected").val(); //<==  add "window." befor th ch_from_year  to use the window scope 
				$( "#ch_to_date" ).datepicker( "option", "minDate", new Date(window.ch_from_year, 1 - 1, 1) ); // <==  Add this line to set the minDate option dynamically
	            $(this).datepicker('setDate', new Date(window.ch_from_year, month, 1)); //<==  also here add "window." befor th ch_from_year  to use the window scope 
	        		        }
    	 	
	});
	
	});

$(function() {
	$('#ch_to_date').datepicker({
		showOn: 'button',
		buttonImage: '../css/images/calendar.gif',
		buttonImageOnly: true,
		changeMonth: true,
		changeYear: true,
		minDate: new Date(ch_from_year, 1 - 1, 1),
		beforeShowDay: hideDays,
	 	yearRange: '1929:2010',
	 		dateFormat: 'mm-yy',
	        onClose: function(dateText, inst) { 
	            var to_month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
	            var to_year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
	            $(this).datepicker('setDate', new Date(to_year, to_month, 1));
	        }
			 	
	});

	});
