jquery flexigrid not getting updated on onClick event

Hello Experts,
I have a drop down where I am displaying some name from the XML file, which ever is been selected from the drop down list box I am displaying results in the Flexigrid.
For some reason it is only functioning for the first on click event and it is not calling proxy.asp on the second click.
Please can someone advice If I am doing anything wrong here.
Many thanks for your help
Regards

The problem is that these two are called immediately in succession, one after the other:
getListRefs();
var sRefNos = $("#listRefnos").val();

getListRefs() makes an asynchronous ajax request. So, it will take some time before the request completes. Hence this:
success: function(msg){
 $("#listRefnos").val( msg );
 }

will assign msg to #listRefnos AFTER the request has completed, but the browser executes  var sRefNos = $("#listRefnos").val();  before the request is completed.

You need to call getListRefs and then provide a callback function that will then do the remaining steps AFTER the request has completed. So, you need to
modify getListRefs and viewList
create a new call back function =>viewListCallBack
 function getListRefs(sListname,callBackFunc)
 
{
 
	$.ajax({
 
	  type: "POST",
 
	  url: "list_builder.asp",
 
	  data: "action=results&listname="+sListname,
 
	  success: function(msg){
		$("#listRefnos").val( msg );		
		callBackFunc();
	  }
 
	});
 
}
 
 
function viewList(){
    
  var sListname = $("#drpLists").val();
  
  if(sListname == 0 || sListname == "new"){  
    alert('Please select a list');
  }else{
   
	getListRefs(sListname,viewListCallBack);		
 
   
  }
 }
 
function viewListCallBack()
{
	var sRefNumbers = $("#listRefnos").val();
alert( sRefNumbers)
	$('#defaultResults').hide();
    var sViewQuery = "SF1=keyword&ST1="+sRefNumbers; 
    
	listViewer("#listDisplay1",sViewQuery);
 
}

You need to double check your server script. Currently, list_proxy.asp is returning this:
 <font face="Arial" size=2>
<p>Microsoft VBScript runtime </font> <font face="Arial" size=2>error '800a0005'</font>
<p><font face="Arial" size=2>Invalid procedure call or argument: 'left'</font><p>
<font face="Arial" size=2>/artism/admin/list_proxy.asp</font><font face="Arial" size=2>, line 24</font>

which is a server-side error.

Hello Hielo,
This error has been fixed but I am not able to assign the result IDs to the query ....

getListRefs();                 --> this actually does ajax call to list_proxy.asp and i see the results back
var sRefNos = $("#listRefnos").val();  --> however i am not able to pick them from here making sRefNos empty ...

thanks
