I'm building a workbook that uses checkboxes to turn pages on or off (via hiding them). What I want to do is hide the coresponding summary in the economic overview page when a particular feature is disabled. However, for whatever reason, I am unable to write a successful program to do this.

My first instinct was to try something like this:

Private Sub CheckBox1_Click()
Application.ScreenUpdating = False
Call Sheets("overview").special
If CheckBox1 = True Then
Range("a18").Select
Selection.EntireRow.Hidden = False
CommandButton7.Visible = True
sheets("overview").select
Range("a66").select
Selection.EntireRow.Hidden = false
sheets("summary").select
Else
If Worksheets("overview").Range("b58").Value = 0 And Worksheets("overview").Range("c58").Value = 0 Then
Range("a18").Select
Selection.EntireRow.Hidden = True
CommandButton7.Visible = False
sheets("overview").select
Range("a66").select
Selection.EntireRow.Hidden = false
sheets("summary").select
Else
Application.ScreenUpdating = True
MsgBox ("The object you have choosen to hide contains values and thus can't be hidden.")
End If
End If
End Sub

That would generate an error during the page switching part of the code. I figured, alright, whatever you stupid program, I'll just work around you. So I wrote a seperate program on the other sheet, and inserted a call program into the code, but that is also generating an error. Thing about it is though, is I know this can be done because I can make a program that sends numbers to a range on the other sheet, I just can't get it to use a true/false value to exicute the program. Any advice?

Call Sheets("Overview").special(1) -> or .special(0)

Sub special(tf)
If tf = 1 Then
Range("a66").Select
Selection.EntireRow.Hidden = False
Else
Range("a66").Select
Selection.EntireRow.Hidden = True
End If
End Sub
