asigning a help topic to a cmd button

[Afrosheen via AccessMonster.com]

Good morning,
I have a help menu [taps-help.chm] and it appears to work when I press {F1}.
I set up the control Help File and left the Help context Id blank {0}.

I went to the button {cmdHelp} and put the Help Context Id to number {30}
which is a page number. When I pressed the button, nothing happens. When I
pressed the {F1} key then it came up.

What I'd like it to do is to (I guess) is when I press the button to have it
emulate the {F1} button.
Can this be done or is there another way?

Thanks for your help and reply.
