Field property - Required

[tblues87]

Hi

I need a little help with this filed property. For one field I set the property "Required" to Yes. When the field is null access gives me a warning massage box (You must enter a value in tblSopl.field) but I want to crate my own warning massage, can someone help if it's possible.

Thanks
