I'm trying to catch the {Escape} key and not allow it to put up an
error when my form is open. I have one of my command buttons set to
cancel true already, but it doesn't always catch the key press. I've
found some mention of using this

On Error GoTo ErrorHandler
Application.EnableCancelKey = xlErrorHandler

But I'm not really sure where to put these lines. I put them in my
UserForm_Initialize sub and I get 'Label not defined' for ErrorHandler
on compile. I'm not exactly sure where I should put this where it
will always be active. Any help would be appreciated.
