Show sheet when userform is shown hide Sheet when userform is closed

I am trying to show sheet3 (named MCR (BLANK)) when ever the Userform1 is initialized and Hide the sheet when Userform1 is terminated.

Tried the code below, but it did nothing, any help or direction would be greatly appreciated.

Private Sub UserForm_Initialize()
Sheets("MCR (BLANK)").Visible = True
End Sub
Private Sub UserForm_Terminate()
Sheets("MCR (BLANK)").Visible =False
End sub
