With this button you can delete existing links for a record, and empty the text field. A control question will appear, asking you to confirm that you want to delete the text. The text phrase will then be deleted from the text register.
Please Note! Before you delete the text, make sure that the text phrase is not linked to other records! If you only want to delete the link but keep the text phrase in the text register, you should instead choose the Purge text button.
