I decided to use a hidden column solution, so now there is no need to check what users are coping/pasting. Anyway it is nice to know that there is such a function in VBA (I don't have help files installed so actually it is really hard for me to check anything). Maybe I am wrong, but should any worksheets function be used in VBA code or it is better to use VBA function instead in any case?
Thx for help,
Best regards,
Tytus
