You can use following VBA code:
You can change the "mysheet" with you sheet  name. It will unhide  the sheet if
it is hideen.


Sub myload()
Dim mkc1 As Error
Dim sheet1 As String
sheet1 = "mysheet"

For Each ws In Worksheets
If ws.Name = sheet1 Then
edits = 1
End If


Next ws

if edits = 0 Then
Else
If Application.Worksheets(sheet1).Visible = True Then
Else
Application.Worksheets(sheet1).Visible = True
End If
End If
End Sub

I hope it works

You can modify the following code  to do what you want:
' This makes all sheets  visible (ie for calculations to be done)
Sub all_visible()

For Each Sh In Sheets
Sh.Visible = True
Next Sh

End Sub

'This makes the following sheets invisible

Sub invisible1()

Worksheets("Instructions").Visible = False
Worksheets("Rankings").Visible = False

End Sub

Thanks for the help. I looked for Hide, but didn't think to look for
Visible. (I am happy to take your admonition to heart, but I think
maybe it makes more sense to ignore the questions that you find
offensively easy.)
