Thanks Kent - I was setting the 'from to' at the bottom and i didn't get the hang of the song offset to allow for the drum count in

still a bit hazy about the whole process but i can play around with it

funnily enough the other tracks that worked had the correct start and end bars entered in the boxes at the top

must just have been a glitch with that file
knew it had to be a simple matter but how that single fle had 1 and 1 I don't know.............

thanks anyway
