@Charlesdh: I'm sorry if I sound a little disturbing, the truth is that I'm just starting to learn VBA and I had a job to do on it. I did the job on a System that runs on Windows OS but the person that examined the program uses MAC OS, so the program didn't work on his System.
I think what I really need now is a code that will check whether the operating system is Windows or MAC - If it's either of the 2 Operating Systems, it should prompt you to select which one to use. I don't know whether you can help me with a code like that? if you can, I'll appreciate it. (Please I will be needing a full and complete code if you can).
I'm sorry for the troubles, and thank you in advance.
