Q: Calling javascript function from Coldfusion Tried to call a javascript popup window using ColdFusion. Have not been able to do it.
The ColdFusion code is straight forward
<cfif notpaid>
    <script type="text/javascript">
    notpaid();
    </script>
</cfif>

It will pop up a window if a person is "notpaid".  I tried it with alert() and it popup the alert box so the problem is not with this ColdFusion code.
One of the associated embedded javascripts is written as:
modalWin = new CreateModalPopUpObject();
modalWin.SetLoadingImagePath("/dev/images/loading.gif");
modalWin.SetCloseButtonImagePath("/dev/images/remove.gif");

function notpaid() {
    modalWin.Draggable=false;
    modalWin.ShowURL('https://www.sample.com/sample.htm', 320, 350, "Heading");
}
function HideModalWindow() {
    modalWin.HideModalPopUp();
    window.document.forms[1].submit();
}

The modalWin.ShowURL is the function that display the popup window and is proven working when it is associated with clicking, i.e. user click on a button and it will pop up the window.  
In the new scenario, I am using ColdFusion to call without user interaction, but it won't pop up the window.  I believe the problem lies with the javascript function notpaid(). I have tried different ways to no avail.  I seen people talking about CF being server-side and javascript being client-side, but I do not know how to make the connection.  I know with some proper code, it can be done.  What am I missing here?  Thanks in advance.

A: I have finally figured it out.  By changing the "function notpaid()"  to:
notpaid = function() {
    modalWin.Draggable=false;
    modalWin.ShowURL("https://www.sample.com/sample.htm", 320, 350, "Heading");
}   

and the pop up worked.  Don't know why, but it did the trick.
