Debugging a VBA Macro

In Word, macros are written in a language called Visual Basic for Applications, or VBA. When you write a macro, you need to test it and correct any errors in the macro. This process is called debugging. The process of debugging a macro is the same as debugging in any other programming language. All you need to do is step through the macro, one command at a time, and make sure it works as you think it should. You do this by viewing both the windows for your macro and a test document. As you step through the macro (using the commands available in the Debug menu of the VBA Editor), you can correct any errors you locate.

As you are debugging macros, you need to make sure you think through every possible way the macro could be used and all the possible conditions that could exist at the time the macro is invoked. Try the macro out in all these ways and under all these conditions. In this way, you will make your macro much more useful.
