It worked, thank you Arun

Thank You, but I am still getting error. Maybe my script has mistake. Can you suggest a script?

I am using Adobe Livecycle

I am getting over/underflow error, below is the formula and related values: UtilizedContractValue = 0ApprovedContractValue = 0 $=(UtilizedContractValue/ApprovedContractValue) When you open the form both values are zero initially. Need help to resolve it trough 'FormCalc'
