Hi Sue - you shouldn't be changing the section count. You should only be changing the Award: click in the Award Name field and select the award you would like for each record (based on the section counts of 2, 6, 10, etc.).
A little explanation: with the main T&T books, it is assumed that the Start Zone has been completed (2 sections, per Awana guidelines) so the first award triggers after 2 sections in the main book and every 4 after that. If your clubbers start work in the main book without completing the Start Zone (so awards are triggering too soon), the solution is to assign the "w/Start Zone" version of the book. This version of the book has the start zone sections included and the first award triggers after any 4 sections are completed. If you open the generic book record for Discovery of Grace w/Start Zone, you will see that the awards trigger for section counts 4, 8, 12, etc.
If this doesn't resolve your issue, please send an email to support with details of what you want to trigger differently. We'll help get it set up for you.
