I have following the instructions on creating my pop-up calendars, but
I'm sharing the workbook and some users are having trouble with the
code. When they open the document and try to click on any cell, the
code window opens and gives them a debug error. This is only
happening with 4 out of 10 users. What's going on?

The problem? 4 out of 10 users are getting a debug error. (of course, the
up side is that 6 out of 10 are not!).

It would help if we knew what the error message says, and it would probably
help YOU determine what's wrong if they would go ahead and hit the [Debug]
button and tell you what line of code is highlighted at the time of the
error. That'll be the line of code that's generating the error.
