Hi Femina,
Its been a while since the Lovelace days! About your xlate, it sounds like that the OBX.572 field is poplulated with probably a two or more subfields. If so, then you will need to specify which subfield you want by adding the .[0] or .[1] at the end. Email me at trioux@tmh.tmc.edu if you want to chat further about it
