Hi guys, Is it possible to check automatically the fomat of the text that we enter in the freetextfield? I need a textfield in which we can enter a number in form like "INT-0001" as the internal reference for a ticket; another textfield in which we can enter a number in form like "EXT-0001" as the external reference for a ticket; the third textfield for ticket location that is obliged to be entered in form like 7311.0260N+01833.4285W. (W: West; S: South; N: North; E: East) So I need the system to check to verify the fomat if the fomat is incorrect, the ticket will be rejected and an explanation will be sent. Best regards, Xiaoxing
