I managed to answer my own question by writing a select statement in SQL. table1 only has the sum of dollar values extracted via a make table query table2 has the sum of dollar values for 2004 and 2005, also from a make table query my third and final make table query for this exercise is an SQL select statement that performs the subtraction This result is then referenced from a field in my Excel worksheet via Data/Import External Data... table1 ParticipantTotals $13,000 table2 2004=$5,000 2005=$7,500 result table sql SELECT ([table1]![PaticipantTotals]-[table2]![2005]) AS totAnnParticipants FROM table1, table2; actual result $5,500 _____ From: Glenda Wells Sent: Tuesday, May 10, 2005 04:39 PM To: 'mso@xxxxxxxxxxxxx' Subject: Access Ref in Query or Excel In an Access query, I need to perform subtraction between two separate tables and can't figure out the reference. I tried this ([table1]![totalField]-[table2]![totalField2]) Actually, if I could reference these two table totals from Excel and do the math there, that would be even better. Any thoughts appreciated. /g ************************************************************* You are receiving this mail because you subscribed to mso@xxxxxxxxxxxxx or MicrosoftOffice@xxxxxxxxxxxxxxxx To send mail to the group, simply address it to mso@xxxxxxxxxxxxx To Unsubscribe from this group, send an email to mso-request@xxxxxxxxxxxxx with the word "unsubscribe" (without the quotes) in the subject line.
