I am receiving a run-time error "13" when I try to run a USerform in VBA.
When I try to debug the problem - I do not get an indication where the
problem is. Below is the code. Does anyone see what might be causing the
error?

Private Sub cmdadd_click()
Dim lRow As Long
Dim lDate As Long
Dim ws As Worksheet
Set ws = Worksheets("Scrip Purchases")

'find first empty row in database
lRow = ws.Cells(Rows.Count, 1) _
..End(xlUp).Offset(1, 0).Row

lDate = Me.txtDate.Value

'check for a family name
If Trim(Me.cbofamily.Value) = "" Then
Me.cbofamily.SetFocus
MsgBox "Please enter family name"
Exit Sub
End If

'copy the data to the database
With ws
..Cells(lRow, 1).Value = Me.txtDate.Value
..Cells(lRow, 2).Value = Me.cbofamily.Value
..Cells(lRow, 3).Value = Me.cbovendor.Value
..Cells(lRow, 4).Value = Me.txtdenomination.Value
..Cells(lRow, 5).Value = Me.txtquantity.Value
End With

'clear the data
Me.txtDate.Value = Format(Date, "medium date")
Me.cbofamily.Value = ""
Me.cbovendor.Value = ""
Me.txtdenomination.Value = ""
Me.txtquantity.Value = ""
Me.txtDate.SetFocus

End Sub

Private Sub cmdclose_Click()
Unload Me

End Sub

Private Sub UserForm_Initialize()
Dim cfamily As Range
Dim cvendor As Range
Dim ws As Worksheet
Set ws = Worksheets("Lookuplists")

For Each cfamily In ws.Range("familylists")
With Me.cbofamily
..AddItem cfamily.Value
..List(.List - 1, 1) = cfamily.Offset(0, 1).Value
End With
Next cfamily

For Each cvendor In ws.Range("vendorlists")
With Me.cbovendor
..AddItem cvendor.Value
..List(.List - 1, 1) = cvendor.Offset(0, 1).Value
End With
Next cvendor

Me.txtdenomination.Value = ""
Me.txtquantity.Value = ""
End Sub
