okay, this should be pretty darned simple, but it seems those are always the things that jump up and bite me

i've created a workbook that has 12 modules and 7 user forms. this workbook will be distrubuted to others, so obvioulsy the best thing to do is to make all the code an add in and have some basic workbook and worksheet functions that call the add in code.
i've gotten that far, and added code that successfully adds the add in at the opening of the workbook. but then it says that it can not see any of my add in module names.
am i referencing them incorrectly? this has to be something that is very simple that i am just having a brain hiccup on....

i.e.

Private Sub Worksheet_Change(ByVal Target As Range

AddInWorksheet_Change Targe

End Su

where AddInWorksheet_Change is defined in the addin workbook as a public sub

Public Sub AddInWorksheet_Change(ByVal Target As Range

Dim sCellAddress As Strin
Dim rNew As Rang
Dim rOld As Rang
etc.....

thanks much
