After solving an earlier query about setting my formula and linking a client and rates table I now need to create a column which averages out my earnings from clients. Should this be in my clients table or do I need to create a separate table for this?
I now have records with the numbers of sessions for each client and total earnings for each client - all in my clients table - so where and how should my average income per client calculation go please?
Thanks in advance
Liz
