mdefs : import @DocumentLayout not in scope

[Thomas McDermott]

My "mydefs" file looks like this:

 import @DocumentLayout
 def @Fish address@hidden FISH}

When I lout (3.18) my book, I get
 mydefs:1:8: import @DocumentLayout not in scope
 mydefs:2:12: fatal error: exiting now

Any clues?

Thanks,
        Tom
