We have a Union query that Union all transactions. We use separate queries to return the totals for separate sections on the Balance sheet. Those are TOTAL QUERIES since they total all transactions against the specific accounts. When there is no transactions against that account, the total will be Null and not zero. When I use the NZ expression it still returns Null. I have used the NZ multiple times on queries that are not TOTAL queries and it worked. Is it because we work with TOTAL queries that it doesn't return 0?
