The expression is meaningless. What are you trying to do? 

Having the exact same issue - would really appreciate help. Can we not do arithmetic with decimal data type if they're in different tables? I am not working with whole numbers, need the decimals... 

Please start a new topic for help with this. Please actually explain your problem there.
