[RESOLVED] Runtime error '91': Object variable or with block not set

[Ehwenomare]

Thanks, it was pretty straightforward using a control array of command buttons and a frame control. Anything else is in the code. Have you used control arrays before?

Did you notice the change in wording from "Computer simulation for…" and "...part 1 and 2" to "Computer simulation of…" and "...parts 1 and 2"?

To hell with whatever that thing says. It has been trashed into the recycle bin. Thanks.
