frustrated w/ commandbar(s)

Trying to get some custom commandbars in my vba form, and I keep getting procedural / argument errors ...

I am using RobDog's http://www.vbforums.com/showthread.php?t=402050 as a guide, but I can't get this line:

Set moCBImage = Application.CommandBars.Add("cbImage", msoBarPopup, , True)

to compile... says illegal arguments...

thanks!

Looking up on MSDN, I'm starting to get very confused with the difference b/w commandbars, commandbar, and how to add objects to these...

Only works the first time I run it... Then I get an invalid argument error...
