Error Arithmetic overflow


Level 1

I have multiple number fields that perform calculations based on GPA, Credits, Quality Points etc.. the last two fields divide previous returned values but when the form opens I get the overflow error.

How do you surround the calculation with a check to assure the variables are non zero, non-null?

How can you prevent the fields from trying to calculate until the form is loaded?

Any help is greatly appreciated.

You should wrap your formula into an if expression.

FormCalc will always create under/overflows when you try to multiply or devide by 0.

if (fieldA ne 0 and fieldB ne 0) then

     ;add your formula here!
