Barbara,

I was going to test that to see, I just hadn't gotten to it yet. As long as BETWEEN is inclusive of the beginning point and exclusive of the end point, which I kind of doubt, I'd bet it is inclusive of both endpoints. And in this case that's significant.

>I've found that the indexed field (or expression) MUST be on the left for Rushmore to work correctly. In your case could you have used a BETWEEN construction?
