What I am trying to work on is about calculation. (refer to attchment - http://www.htmlforums.com/attachment.php?s=&postid=198089 - http://www.htmlforums.com/attachment.php?s=&postid=19808 9 ). The price is readonly but the quantity is changable. What I want is the total colum will automatically calculate (price * quantity) with onchange of quantity textbox. Meaning when there is any changes of quantity texbox's value, then total column value will automatically calculated.

My existing code is below but I wonder if this way works:

function calculate()
{
tempquantity = document.myform.quantity_fr.value;
tempprice = document.myform.price_fr.value;
temptotal = tempquantity * tempprice;
}
document.myform.total_fr.value = temptotal
}

<%
DO WHILE NOT rs.eof
response.Write "<tr valign=top><td>" & rs("pName") & "</td>"
response.write "<td nowrap>" & rs("PCategory") & " </td>"
response.write "<td nowrap>" & rs("PType") & " </td>"
response.write "<td nowrap align=right><input type=text name=price_fr size=5 readonly value=" & rs("PPrice") & "> </td>"
response.Write "<td nowrap><input type=text name=quantity_fr size=5 maxlength=6 value=" & rs("quantity") & " onChange='calculate();'></td>"
response.write "<td nowrap align=right><input type=text name=total_fr size=5 readonly></td>"
response.write "<td><input type=hidden name='productID_fr' value=" & rs("RDetails.ProductID") & "></td></tr>"
strGrandTotal = cdbl(strGrandTotal) + cdbl(strTotal)
rs.MoveNext
LOOP
response.write "<tr><td colspan=6 align=right bgcolor=orange><b>Grand Total = " & FormatNumber(strGrandTotal,2) & "</b></td></tr>"
%>

people on this forum: if you are looking for help, it sure in heck helps if you at least make an attempt of being descriptive in what's wrong other than the useless "i got an error"....
