When you hide a sheet using hidden or very hidden and then you want
to use a macro to view the sheet you will need to tell the procedure
to un-hide the sheet first, to do this use the following code

Private Sub CommandButton1_Click()
Sheets("instructions").Visible = True
Sheets("instructions").Select

End Sub

Then put the following code in the instructions sheet

Sub worksheet_deactivate()
Sheets("instructions").Visible = xlSheetVeryHidden

End Sub

And when you click off the sheet it will hide it again.
If you passworded the sheet you would have to do the same for the
password as for the hidden sheet.

Thank you for the help, but I never hid the sheet, I just protected
it. The macro works when the sheet is unprotected, but will not
work when protected. I have other macros that go to other tabs that
still work when I protect it, just not this one. Any further
suggestions?

I wonder if the other sheets have one or more unprotected cells and this sheet
has all its cells protected? Could you unprotect a blank cell so this cell
can have the focus when the sheet is selected?
