Assuming you're talking to changes to the <i>Table</i> itself...<br>Use MsysObjects, the DateModified field. Read that field at your chosen event/interval, by Object Name, and you can store it in another table, then compare it against the last event/interval in which you checked that objects date .<br><br>If you meant changes to the <i>Records</i> in the table, then you need to know <b>all</b> avenues of data entry/updates, and have a 'date changed' field in the table, and write the current date to that field on an AfterUpdate event, or after any code which changes the data.<br>--Jim
