Am working with a fairly large DB, 50MB, and need to select groups of records based upon the value of one field. This field is a text field which contains only numbers. Normally I merely enter the value I want to extract and the query works fine, except on this one field. Nothing I've read in any of several manuals indicates a problem but when I enter a value in the criteria row, I get a blank datasheet. If I use any of the comparison operators, I get the complete listing. I tried to convert the field to a numeric field but receive an error message that insufficient disk space or memory exists. System has 20 GB hard drive and 384 MB RAM. Am at a loss as to how to proceed. Suggestions gratefully accepted.
