cheers Deepak, the ID variable itself was fine, the problem was the last
file separation character in the filepath - ie the '\' - was being
interporeted as an escape character which prevented the variable from being
recognised and expanded. Once I escaped the '\' everything worked
correctly. Took quite a while for the penny to drop though - its a bit of a
Gotcha.
