I'm trying to concatenate (CONCAT) two variables, but I keep getting this error message: "Invalid combination of data types in an assignment. Character strings may only be assigned to string variables. Numeric and logical quantities may only be assigned to numeric variables. Consider using the String or Number function." The variables consist of numbers, but I've labeled them as String in data view. I tried using the String funtion in Transform -> Compute Variable, but it won't let me do that either. The command is apparently STRING(numexpr,format) but I have no idea what to put in for format, so I'm getting the error message "The string arguement required for the function specified was not supplied." PLEASE can anyone help? This is giving me an ulcer.
