Concatenate error help

[Tuan]

Dear All

The concat function seems strange when I want to combine fields to one. The compile error is : ERROR: Invalid variable type near line... Any help appreciated.

Hi

I want to recall the previous post. The error was because the concat function only combine strings to string and not the number.Tks for reading.

If you want to convert numbers to strings, you can use the edit or the maketext functions.
