In the Orders form, users often have a need to return to the first record. Because there are many employee records, it may take a long time for them to scroll up to the first record, so you create a button with the label First Record.When users click the first Record button, you want to display your own custom message instead of the system message "FRM-40100: At first record."The system message should be displayed in other cases when users attempt to scroll above the first record.You code the following When-Button-Pressed trigger::SYSTEM.mesage_level := '5'UP;WHILE FORM_SUCCESS LOOP -UP;END LOOP;MESSAGE ('This is the first Order');The button works perfectly to return to the first record and display your custom message instead of the system message. However, users report that as they continue to use the form after clicking the button, no longer see other helpful messages. For example, the message "FRM 40102: Record must be entered or deleted first" no longer appears when they attempt to scroll past the last record.How can you resolve this Issue so that all system messages continue to be displayed after the trigger code runs?
