    <cfset Id = getRpcmtHistory.LeadId> /Id is the variable that has numeric value
    <a href="javascript : poponload();">

    /what should I put in () when I put Id it gave me an error that Id is not identify.

    I'm not too familiar with ColdFusion but this is how we usually pass a variable to a function in javascript:
    
<html>
<body>

<script type="text/javascript">
function watever (the_variable) {
   alert(the_variable);
}
</script>

<a href="#" onclick="watever('YES');">Link</a>
</body>
</html>
    HTML:
    Also, keep in mind on what you're passing because '5' and 5 are not the same.

    Thanks for the reply, in this case YES has been pass to the function as a fix string, I want to pass variable for example consider Var Id;
    Id sometime is 1, or 2, or 3, and so on so I need to send variable Id not the actual 1,2, 3.

    <cfset Id = getRpcmtHistory.LeadId[i]>

<script type="text/javascript"  language="JavaScript">
    <cfoutput>
        var #toScript(Id, "ident")#;
    </cfoutput>
</script>
    Code (markup):
    This should create a JavaScript variable called ident holding the value of Id ( ColdFusion ).

    ** I'm not by any means a ColdFusion expert but it *should* work as expected.
