Calculation based on results of 2 expressions

[MarthaNH]

I have a field called Reoffense Counter and a field called Counter, where
Counter is the total count of all the records, and Reoffense Counter is the
total of only those records where a new offense has taken place. Each of
these fields contains a "1" where appropriate, so they can be counted. I
want to find out what percentage of the records contain a Reoffense, so I
think I would want to divide Reoffense Counter by Counter. I haven't been
able to come up with the correct expression to use in my report. Can you
help?

In this query use your table and field names --
SELECT Sum([Reoffense Counter]) / Sum([Counter]) * 100 AS [Re-offend Percent]
FROM YourTable;

Thank you, Karl. I tried entering this as a query and I also tried inserting
it into a text box as an expression in the report, but I keep getting a
Syntax Error. Perhaps there is something missing that my inexperience
doesn't make clear to me?

In query design view use this as a calculated field --
Re-offend Percent: Sum([Reoffense Counter]) / Sum([Counter]) * 100

For some reason, I keep getting error messages. I'm probably trying to enter
the expression in the wrong place. In query design view, is this expression
placed in the "Field" row or in the "Criteria" row? Thank you for your
patience.

Karl - Please disregard my previous message. I'm not sure what I was doing
wrong yesterday, but I went back and created the calculated field in the
report design view, and it works now. Thanks so much for all your help!
