Tom,

Yikes! My apologies, Tom. I didn't say I was a _good_ tester - it works
90% of the time (for large populations of reference numbers) and 100% of the
time on the value that I used to test it... ;-)

Bernie's will work with a straight 4 digit number

Which shouldn't be there per the original post.

And where's that darned "retract post" command when you need it....
