Crystal 8.0 record selection using SQL Expression field

I have created a ODBC report using the SQL-92 3.6 driver. I created the
following SQl expression {fn SUBSTRING(
"PUB"."OrderHed"."SalesRepList",1,3)} The field displays fine in the report.
When I try to use the field in my record selection I get the following
error. Progress error Column not found/specified (7520). The two Progress KB
articles regarding error 7520 do not apply to record selection. Any ideas?
