Actually I did put line numbers, and I did put error handlers in almost every sub/function, but the guy just saw a message, and clicked OK, then told me it does not work. Quoting him: "(A pop up saying error 15 or something like that)."

I just sent him an e-mail to send me a details on the message he gets, or a screen shot of the message. I made the program give the exact location of the error, as in the form, sub/function, line #, and error #, and description.

At this point, I'm hoping that the error is in the sub/function that have error handler, because I did not set it in all the functions.

I wanted to have an idea on the problem before I send the e-mail to him, that's why I looked for the description of the error, but I could not find it anywhere !
