[RESOLVED] firing javascript on OnCheckChanged radiobutton event

[drpcken]

I have some javascript that I'm trying to fire off when the checked status of a radiobutton is changed. its suppose to uncheck any checkboxes that are checked on my page. the checkboxes are named CheckBox1, CheckBox2, etc. Here is my javascript

	<script type = "text/javascript">
	function uncheckAll() 
			{
				for (var j = 1; j <= 14; j++) 
				{
					box = eval("document.Form1.CheckBox" + j); 
					if (box.checked == true) box.checked = false;
				}
			}
       </script>

and here is my code in my html:

<asp:RadioButton id="OptionButton3"  OnCheckedChanged="uncheckAll()" runat="server" Text="CONCENTRIC OR COMPRESSED" GroupName="CableType"></asp:RadioButton>

But when I load the page i get this error:


Compiler Error Message: BC30456: 'uncheckAll' is not a member of 'ASP._500_10_aspx'.


I'm coding in VS.net. Why can't it recognize it?
Thank you!
