So VERY True, Too many late nights and I really do appreciate your input as 
this gave me food for thought and I now have EVERYTHING Working.

Both for Traffic & Session USAGE.

For Usage, I still had to use Max-Monthly-Traffic as a Check := and based on 
sqlcounter calc, do a Reply = Sessions-Octets-Limit = XXXXXX on the 
Access-Accept as this is supported by the ppp 2.4.4 NAS.

What I would like to know now, is how I can use sqlcounter to do a Month 
Calculation based on the date of the account being registered and NOT the 
Calander Month?  Anyone?
