Hello! I got this piece of code from someone who helped me with a function
that counts the number of textboxes in a user form. However I do not not what
what 'oUF' means and how to use the function. I have never used functions
before so I do not know how to call it. I tried useing 'Call countTextboxes'
in another Sub but I suppose that you need something else...

Public Function countTextboxes(oUF As UserForm) As Long
Dim iCtrl As Long
For iCtrl = 0 To oUF.Controls.Count - 1
If TypeName(oUF.Controls(iCtrl)) = "TextBox" Then
countTextboxes = countTextboxes + 1
End If
Next iCtrl
End Function
