A quick one, Use when-validate-item trigger, check text entered by using INSTR function

Yes but if the value was wrong then I need to back to same field with massage. In this case I can not use GO_ITEM procedure in when validate item Trigger. Please advice?

Thanks

If when_validate_item trigger fails, user can not navigate to another field. So you do not need go_item to go to the same field. So if ? mark is entered, you should fail the when_validate_item trigger by using RAISE FORM_TRIGGER_FAILURE.

'Go_item' is an illegal command in the 'when-validate-item' trigger so you don't have to worry about issuing that command.
