Hi I use the following code to try to get the pointer value from an editable linear gauge. 
The Jscript: 
  <script language="javascript"> 
	  //FC_ChartUpdated method is called when user has changed pointer value.  
	  function FC_ChartUpdated(DOMId){ 
		 alert("in function"); 
		 alert(DOMId); 
		 //Check if DOMId is that of the chart we want 
		 if (DOMId=="myChartId"){ 
		     
		    alert ("passed check"); 
		    //Get reference to the chart 
		    var chartRef = getChartFromId(DOMId); 
		    //Get the changed value 
		    var pointerValue = chartRef.getData(0);  
		   alert(pointerValue);  
		 } 
	  }  
   </script>    
Currently the DOMId I pass in is the ID of the Chart object as per: 
var myChart = new FusionCharts("fusion/Charts/HLinearGauge.swf", "myChartId", "450", "120", "0", "0"); 
myChart.setDataURL("Data/Linear3.xml"); 
This is how I call the function to get the value: 
<input type="button" name="test" value="test" onClick="javascript:FC_ChartUpdated(myChartId)"> 
2 Questions stem from this: 
1. Upon clicking the button, I never get the alert "passed check" which means the DOMId isn't getting matched..... what am I doing wrong here? 
2. How do I actually take the value and instead of putting it into an alert box, actually add it into the post or put variables when the form submits? is there a way to write it to the value of a hidden field? 
Thanks in Advance, 
Ken
