Excel VBA: Compile Error: Method or data member not found - vba

Question

EDIT: To clarify, the code seen below is within a module and the UserForm is all contained within its own code.
I have the following code. When I go to run it, Excel throws me a compile error: Method or data member not found and highlights the following piece of code: .showInputsDialog. I have no idea how to resolve this error.
To give more information, the sub sportUserForm is supposed to call up a UserForm sportsUsrFrm. Any help with this issue is greatly appreciated.
Option Explicit
Sub sportUserForm()
Dim sSport As String, sPreference As String
If sportsUsrFrm.showInputsDialog(sSport, sPreference) Then
MsgBox "Your favorite sport is " & sSport & ", and you usually " _
& sPreference & "."
Else
MsgBox "Sorry you don't want to play."
End If
End Sub
Public Function showInputsDialog(sSports As String, sPreference As String) As Boolean
Call Initialize
Me.Show
If Not cancel Then
If optBaseball.Value Then sSport = "Baseball"
ElseIf optBasketball.Value Then sSport = "Basketball"
Elss sSport = "Football"
End If
If optTV.Value Then sPreference = "watch on TV" _
Else: sPreference = "go to games"
End If
showInputsDialog = Not cancel
Unload Me
End Function
UserForm code for sportUsrFrm
Option Explicit
Private Sub cmdCnl_Click()
Me.Hide
cancel = True
End Sub
Private Sub cmdOK_Click()
If Valid Then Me.Hide
cancel = False
End Sub

Answer 1

You're getting the error because showInputsDialog isn't a member of the form, it's a member of the module you're calling it from. You should also be getting compiler errors on these two lines...
Call Initialize
Me.Show
...because you seem to be getting the module and form code mixed up.
That said, you're overthinking this. A UserForm is a class module, and it can be stored in a variable (or in this case, in a With block), and can have properties. I'd add a Cancelled property to the form:
'In sportsUsrFrm
Option Explicit
Private mCancel As Boolean
Public Property Get Cancelled() As Boolean
Cancelled = mCancel
End Property
Private Sub cmdCnl_Click()
Me.Hide
mCancel = True
End Sub
Private Sub cmdOK_Click()
If Valid Then Me.Hide '<-- You still need to implement `Valid`
End Sub
And then call it like this:
Sub sportUserForm()
With New sportsUsrFrm
.Show
Dim sSport As String, sPreference As String
If Not .Cancelled Then
If .optBaseball.Value Then
sSport = "Baseball"
ElseIf .optBasketball.Value Then
sSport = "Basketball"
Else
sSport = "Football"
End If
If .optTV.Value Then
sPreference = "watch on TV"
Else
sPreference = "go to games"
End If
MsgBox "Your favorite sport is " & sSport & ", and you usually " _
& sPreference & "."
Else
MsgBox "Sorry you don't want to play."
End If
End With
End Sub
