I have a user form with several Check Boxes that are for controlling
worksheets in a workbook.

Each check box is for hiding or unhiding the different worksheets in a
workbook from the user form2.

Workbook name = Installer Forms
Worksheet name = Sheet 1
Checkbox names = Office_Package_Preparations_101

I want when the Box is checked for the worksheet to be shown and when the
box is not checked for the worksheet to be hidden.

Hi Brian,

Important consideration is that you cannot hide all sheets so must test for
at least 2 visible sheets before hiding a sheet. If only one sheet visible
then unchecking the last checkbox is ignored and it is re-checked. All of
your CheckBox code should be like the following.

You could if you wish place the main code in a standard module and call it
from the CheckBox click events and pass the worksheet name to the code.

Private Sub ChkSht1_Click()

Dim ws As Worksheet
Dim i As Long

'Edit ChkSht1 to your CheckBox Name
If Me.ChkSht1 = True Then
'Edit "Sheet1" to your sheet name
Sheets("Sheet1").Visible = True
Else
'Cannot hide all sheets so at least
'2 must be visible before hiding one.
For Each ws In Worksheets
If ws.Visible Then
i = i + 1
If i 1 Then Exit For
End If
Next ws

If i 1 Then
Sheets("Sheet1").Visible = False
Else
'Set back to True (Visible)
Me.ChkSht1 = True
End If
End If
End Sub
