It's not because of %chan, %chan is set either by the parameters passed to the alias or by $mnick. You should have more scopes listed for your channel, but I'll guess that's just because you didn't show the whole file.
The only thing that could be preventing the menu from showing is syntax errors or missing parts to the script. Could you please paste the exact errors you're getting and the entire contents of the script file here:
