Memory problems?

J

Jack

Hi,
Would greatly appreciate advice on whether the following query results in
memory issues (error message like "can't read memory written to 0X00000" as
well as random hanging/no response):

Query extracts top 10 records using the Top Value function based on a
calculated field sorted in the descending order using Access' standard sort
function. The calculated field contains the formula:
if(isNull(fieldB),-fieldA,fieldB-Nz(fieldA))
I used Nz as fieldA and fieldB could potentially be null fields.

Problems more frequently encountered when a form is used to preview a report
containing the results of this query.

Thanks much!
