hi nigel,
if the layout was wrong, it would never work. I always build my string the same way (for the same graph). It works fine after a reboot, but with the same string. But i may try to put it on a form, and then fill the datasheet 'manually' (that is, by scanning the datasheet, if i can manipulate it in graph 5).
greetings
derk
