You cannot just change this one single statement to use the video unit without changing the rest of the program. Well, you can, but it won't do anything. The video unit does not automamagically know what has been written to the screen in other code.

Consider rewriting the logic of this code (keep track via a variable whether the error message has already been written) instead of trying to literally translate this hack.
