I imported data from cvs file to Access 2003 database, made Query1 and calculated "G". Then I made Query2 by selecting people's IDs and "G" from Query1. What I want to do is to filter people whose "G" values are less than 20, so I entered "<20" in the Criteria box. However, a error window popped up indicating "Internal OLE Automation Error". There was no other choice but clicking "OK".



I am not sure which step is wrong. Could you please help me with that? Thanks a lot!
