What does the following code mean?
on click (if the button was not clicked?), is this contradicting itself?

<a href="#" ID="btnCalculate" NAME="btnCalculate" onclick="if(clicked == 0){CalculateAllPayments()}">

Thanks

anchor tags (i.e., "a") don't have a clicked attribute.  So, I think that this reference to "clicked" is to a global variable.

Yeah, this demonstrates it.

Change the value of "clicked" to true, or false, and click on the "here' link
<html>
<body>
 
<script type='text/javascript'>
var clicked = false
</script>
 
<a href="#" onclick="alert(clicked)">here</a>
 
</body>
</html>

You are correct because I found the variable that sets the value of clicked on formsubmit()

function frmPayments_onsubmit()
{
      clicked = 1;

...............
