Add parameter to AJAX in Classic ASP

In addition to "PaymentID" need to add another parameter to exiting AJAX call for variable "CurrUserID", see existing code below:

<script>
     function cback_<%=objRS("PaymentID")%>(text) 
              document.getElementById('tr_<%=objRS("PaymentID")%>').innerHTML = text;
      }
      doAjax('/receipt_ajax.asp','PaymentID=<%=objRS("PaymentID")%>','cback_<%=objRS("PaymentID")%>','get','0')
</script>

Need help on Syntax, I have tried adding comma plus Parmenter and concatenating using & or +

Solution

The URL syntax is page.asp?key1=val1&key2=val2, so your code most likely needs to be

doAjax('/receipt_ajax.asp',
'PaymentID=<%=objRS("PaymentID")%>&CurrUserID=<%=objRS("CurrUserID")%>'

where <%= %> injects the server side value to output the value of objRS("CurrUserID"). If all is correct, the page code will get

 doAjax('/receipt_ajax.asp','PaymentID=...&CurrUserID=...'
