Judith-- Because of the special way Access stores date/time data, to properly calculate based in such fields you should use the easy-to-understand DateAdd and DateDiff functions; you can find information on both in Access help. --Jim -----Original Message----- From: mso-bounce@xxxxxxxxxxxxx [mailto:mso-bounce@xxxxxxxxxxxxx] On Behalf Of Judith Fandrich Sent: Thursday, August 11, 2005 13:14 PM To: mso@xxxxxxxxxxxxx Subject: [mso] Access subtracting hours/minutes/seconds Hi all! I have a StartTime, EndTime and a Length. StartTime and EndTime record hours minutes and seconds. Length gets the answer as set up =[EndTime]-[StartTime]. It only works when there are numbers in the minutes and/or seconds but when there is a number in the hours it does not sutract correctly. I would really appreciate some help on this one. Sorry to be so wordy.
