Re: Forms questions.. Help please

(1) you already have a new record in the specified block, thus it will not allowed you to create a new one. check the :system.record_status first before issuing your statement.
(2) use key-exit to capture this condition. Within this trigger, test for :system.mode. If its value is ENTER-QUERY, then your screen is currently in query mode.
(3) don't use post-text-item trigger then! use when-validate-item trigger which will be fired when the user tries to leave the field. If you raise an exception within that trigger, the cursor will stay in the same field.
