How to ensure the required field is not empty when the record is created?
653340Aug 7 2008 — edited Aug 22 2008I have already added a function to the HTML header attribute and managed to popup an error message when the text field is empty. So how do I popup an error message when the select list and popup LOV is unselected?
And above all the issues, the record will be able to add although a popup message is given, how do I prevent the record from adding if there is any required field is empty or unselected?
