Reset Page counter for page numbering

[lanm]

This is what I've tried so far, but it resets on every page.
So, each page is 1 even if the Unique ID spans 2-3 pages.
I only need it to reset on a new field grouping of the list object.


Here's the VB code for the report:

Shared offset As Integer

Public Function GetPN(reset As Boolean, pagenumber As Integer) As Integer
If reset
offset = pagenumber - 1
End If
Return pagenumber - offset
End Function

***************************

In the header, I have a textbox named "tag"

In the footer, I've got the following expression:
="Unique ID Page: " & Code.GetPN(Not(ReportItems!tag.Value Is Nothing),Globals!PageNumber)

My fault...I had the textbox "tag" in the page header and not in the list object itself.

It works!

Thanks!
