but keep in mind that eval() is a little slower in processing time bacause you are first converting a string value, then interpreting it. While I know it's needed quite often, I would try to avoid the use of eval() whenever possible - especially if you are dealing with numeric values. Also, in this case if your numbers are formatted, then eval() will end up raising an error.
My thoughts.

A quick test in IE javascript showed it to work there also.

I tried that earlier but that only concatenates it -----Original Message----- From: Stephen Kellogg [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 23, 2002 10:08 AM To: CF-Talk Subject: RE: OT javascript addition Tim, try adding () around the addition part like so: if ((document.newBillingInfo.SCEPbilledAmount.value + document.newBillingInfo.SCEPpenaltyAmount.value + document.newBillingInfo.SCEPdelinquentAmount.value) != document.newBillingInfo.SCEPtotalAmount.value) This should force the addition to take place before the comparison. PS are you checking for numeric input only This could be done like so: if ((isNaN(document.newBillingInfo.SCEPbilledAmount.value)) || (isNaN(document.newBillingInfo.SCEPpenaltyAmount.value)) || (isNaN(document.newBillingInfo.SCEPdelinquentAmount.value)) || (isNaN(document.newBillingInfo.SCEPtotalAmount.value)) { alert("The amounts must be numeric, Please check the values.") document.newBillingInfo.SCEPbilledAmount.focus() return false; } else { if ((document.newBillingInfo.SCEPbilledAmount.value + document.newBillingInfo.SCEPpenaltyAmount.value + document.newBillingInfo.SCEPdelinquentAmount.value) != document.newBillingInfo.SCEPtotalAmount.value) { alert("The total Billing amount does not add up correctly, Please check the values.") document.newBillingInfo.SCEPbilledAmount.focus() return false; } return true; } } or something like that ;-) this is untested code but hopefully will give you something to work with.
