Actually let me reword this because Tomi's answer won't quite work. The
table has a field called Rating. A number 1 is stored to represent positive
a 2 is stored for neutral and a 3 is stored for negative. I need to query
that will query up all the number 1's (positives) and subtract all the
number 3's (negatives) to give me a true rating. Any ideas?
