Addon adds slash command but it doesn't work
 

Problem solved, a minor code error.

It'd better if you keep your old question, and update it with the solution so others can benefit from it ;)
Now we only got a dead thread without any content here.

My apologies for that. I only skipped posting the solution because I just made a stupid coding error, i.e. failed to prefix a function name with a table name. I didn't think anyone would be interested in my stuff-up :) . But I'll keep that in mind for the future, thanks.
