Thanks Peter.

I realized after posting my question that it wasn't actually Cocoa-related,
nor even Objective-C related - the error was a result of my inexperience

Apologies to everyone for posting off-topic. I appreciate that this is a
high-volume list and didn't intend to distract from the useful discussions
that generally take place here.

Steve
