Another workaround is using the old "subtract zero" trick: if ((document.newBillingInfo.SCEPbilledAmount.value-0) + (document.newBillingInfo.SCEPpenaltyAmount.value-0) + (document.newBillingInfo.SCEPdelinquentAmount.value-0) != (document.newBillingInfo.SCEPtotalAmount.value-0))
This forces JavaScript to recast the values as numbers. Chris Lofback Sr. Web Developer TRX Integration 28051 US 19 N., Ste.

This works FOR SURE: eval(document.newBillingInfo.SCEPbilledAmount.value.valueOf())+eval(document newBillingInfo.SCEPpenaltyAmount.value.valueOf()) Using the valueOf() function converts a string to a number.
