    1. Add the record anyways (I am assuming it gives a database error because of a primary key error) and trap for the error number.<BR>To write out the error use <BR>on Error resume next<BR>before the addnew and after it use<BR>response.write err.number<BR>Then whatever this error number is, you trap for it by using<BR>on error resume next<BR>rs.addnew<BR>if err.number = -21254325543(whatever) Then<BR> response.write "record already exists"<BR>end if<BR><BR><BR>2. Do a SQL statement using the criteria you have and then check for EOF. If at EOF then there is no record and you can safely call addnew.
