Compile Error: Argument Not Optional

[bg18461]

I am trying to create the ACCDE front end but I am running into errors creating it. This led me into compiling my VBA code and I get the "Argument Not Optional" error highlight "Month" in the Function below. This function is used in Access while running a make table query. Any ideas on how to resolve this, I am new to all this, thanks!

Option Compare Database
Option Explicit
 
Function LoadFactor1to12()
     Select Case Month
End Function

MOnth is a VBA Function that requires an argument. Have you looked up Month() in help yet?
