hi les, Thanks for the reply. I know what the definition and declaration blocks are. What I was asking is where did it appear from in your example? You said, add the doc statement to the file, but afterwards, you mentioned it again. I mixed up what you were saying. Been working too hard I think. Anyway, I'll try it again when I get some time. I need to get this fixed for future use. Re the stripped out channels - I've already tried pasting them back in. A resave just strips them out again. Bummer. cheers mac
