I am trying to find a way to automatically add a word to the end of a string when someone enters something into a cell in column A. For example, if I enter '123123' the macro would add 'Test' to the end resulting in '123123 Test'. However, if I enter '123123 Test' it would leave the cell alone and not add another 'Test' to the end. I am looking for a way to have this done when a person edits a cell and not have to run a macro from the macro menu each time. Any ideas?
