I have the following program that takes a date input from a combo box in a
userform and processes it.

Public Sub TribeNameServDate()
Unload frmFacil
frmTribeNameSMCY.Show
Application.ScreenUpdating = False

Unload frmTribeNameSMCY

ws.Range("A1").Value = sTribeNameUI & " Turnaround Report"

ws.Range("D3").Value = sServMonthUI
iServMonth = Month(DateValue(ws.Range("d3") & " 1,2009"))
iPayrollMonth = iServMonth + 1

If iPayrollMonth 12 Then
iPayrollMonth = iPayrollMonth - 12
End If
'#### How to force this to show a leadning zero for 1 digit nos.? ###
sPayrollMonth = Format(28 * iPayrollMonth, "MMM") 'converts integer month
to text month
ws.Range("C3").Value = sPayrollMonth

If iPayrollMonth < 6 Then
sSFY = Right(sCYUI, 2)
Else
sSFY = Right(sCYUI + 1, 2)
End If

ws.Range("J3:K3").Select
Selection.NumberFormat = "@"
ws.Range("J3") = Right(sCYUI, 2)
ws.Range("K3") = sSFY
Application.ScreenUpdating = True
ws.Range("A1").Select

End Sub

Later, the variable iPayrollMonth will be used to name the file (see
below), and I want it always as a 2 digit number, like 04 instead of 4. How
do I do that?

Public Sub FileNameandSave()
Dim sYear As String
Dim sFilename As String

ActiveWorkbook.SaveAs Filename:="SFY" & sSFY & "." & iPayrollMonth _
& " " & sTribeNameUI & " TR"
End Sub

Thanks!
