Ah, yes, I see now! I was expecting to right-click the command button in design mode and from there be taken into a nice cozy VBA development environment but this is a little more "raw" than that.
I think I'm OK now so thanks for the help, Diane.
I know this should be SO simple but I can't figure it out and it's driving me nuts!
I've set up a new custom eMail form and added a Command Button which should run some code when it's clicked - don't worry about what the code is to do, that's irrelevant at the moment. HOW DO I TELL THE BUTTON...
