I am causing a form to open when the 'Not in List' event occurs to a combo box, to allow a value to be entered to a table. This works fine but How do I stop the Info Message Box appearing, which says:<br><br>The Text you entered isnt an item in the List.<br><br>It doesnt seem to respond to: <br><br>'On Error'<br><br>or 'If DataErr = ...'<br><br>ways to supress most system errors.<br><br>Regards,<br><br>Simon Osborne
