I have the following code:

Option Explicit

Sub ControlForms(varCode)

If Chr(varCode) = "A" Then
Unload AddOrFind
AddTitle.Show
ElseIf Chr(varCode) = "F" Then
Unload AddOrFind
GetTitle.Show
ElseIf Chr(varCode) = "V" Then
Unload AddOrFind
Summary.Show
End If

End Sub

Private Sub AddButton_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, _
ByVal Shift As Integer)
ControlForms KeyCode
End Sub

Private Sub FindButton_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, _
ByVal Shift As Integer)
ControlForms KeyCode
End Sub

Private Sub SummaryButton_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, _
ByVal Shift As Integer)
ControlForms KeyCode
End Sub

When I press 'a' I get the desired result (AddOrFind userform pops up).
When I press 'f' I get error 91 (Object variable or With Block variable not
set) at GetTitle.Show. When I press 'v' I get error 438 (Object doesn't
support this property or method) at Summary.Show. I have verified both
userforms are under the correct name and the code compiles. What's the
problem?
