I have a report that calculates the average of a requested field. The average
is not correct due to "0" values in some of the records. What expression do I
use in the Control Source to ignore the 0 entries? I tried to adapt the one I
use in Excel but did not get the results I was looking for.
Thanks for the help.

Consider stepping back and doing the selection and averaging in a query on
which you then base your report.

If you don't wish to include rows whose value in the field is 0, exclude
them from the query.

If you want zero excluded from the calculation, then use a formula like

Avg(IIF(SomeField=0,Null,SomeField))
