[AccessD] SQL between

Thanks for the responses to this.

I had actually composed this at the same time as the Query Oddity message. I
believe it probably is a DateTime type issue again. 

I'm now going through all DateTime related items and making sure they
reference the new functions I added which eliminates this issue.

I'll review the rest of my messages concerning my newly found issues before
sending them to the list.

Sorry for the confusion.
