Debugging with d() not working?

[Rugnir_viking]

I seem to have a huge problem with following some of the basic addon tutorials.

Originally i thought the code was being complied but not run at all (errors fired when I made syntax error but no output whatsoever)

But it turns out that when I forged ahead anyway, xml and all that jazz works fine. It just seems that no kind of d() debug output actually appears in my chat

Its been annoying me for ages now.

Any solutions?
