The value entered does not match the format of the field
Please help! I am fairly new with using adobe and creating javascript equations. I have run into the error that many new user have, the dreaded "The value entered does not match the format of the field" pop-up. This only occurs when the value answer is 0...
I am creating a till balance form for a retail company, so having that 0 value show is important and fairly frequent, as you want the till to show 0 variance.

Here are the columns Cash(Counted) = AMCash
Cash on Shift Report = AMPOSCash
For the Cash +/- I have a Simplified Field Notation set as AMCash-AMPOSCash
The format is Number to the second decimal point, which I need since we are talking money.
It does the math just fine, but I meet an error when the total is 0 for that column.
I have spent so long on trying to get this to function properly. Please help me if you can!!! Thank you!
