I want to use a unified "UserForm" or any other Screen-Drop to address messages to the excel sheet user whenever there is an error instead of MsgBos.

Question

While the user is using my excel sheet, instead of using MsgBox function, I want to use sort of a standard form with variable messages ; for example:

if I can Call a procedure with ms1 & ms2 as message lines, and this procedure will pop-out including the 2 lines ms1 & ms2.

Thanks in advance for your help.
