How to reference Controls in a Userform based on the control's tabindex instead of name?

In the OP, you said that you want the next in tab order control after the active control

Thanks for all the help. mikerickson, your answer is a perfectly applicable response to my very inapplicable question... What I was trying to do was way off base from what I needed to do. The eventual solution was based in a combination of control change and before_update events, and thus, selecting the next control in the tab index order actually would have failed on some occasions because the next control in line wasn't always visible. It actually needed to be name based, and since I renamed all of the controls with names that could be referred to by each event based on the name of the active control, I could have written a set of macros that could be run each time a change or before_update event happened in each control. Before realizing this potential, I had already written all of the code necessary to make it happen anyway... Thanks for all your help. I have marked this post as solved.
