Then in your search parameters, compare the values in the NEWNUM field instead of SEARCH_FIELD field.Maybe there's an easier way, but this will work as long as you remember to also write a value to the NEWNUM field after every append or replace ... :)================================ Kenneth Grome, WebDNA Consultant 808-737-6499 http://webdna.net ================================------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
