Calculating transactions by time

[sabunim]

Here's my problem, I have customer transaction data that shows deposits and
withdrawals for a month. My data includes the customer ID, type of trans,
date of trans, time of trans and amount. I am trying to come up with a way
to count the number of times a customer makes a deposit then immediately
makes a withdrawal. Obviously this will occur on the same date and within a
minute or less of the deposit. I can pull a query showing the two relevent
transactions together in a table but how do I count the number of
occurrences. Any help is appreciated. Thanks!

SELECT COUNT()
Look it up in Help.

Have you checked to see if the Totals query can do the calculating you need?
Try the Count aggregation...

Excellent! I followed your thought process, tweaked it a bit and got it work
for me. Thank you!
