that sounds like you're not giving it the right table.  double check for typos 
and scope.  maybe you're setting a local 'disp' and accessing a global 'disp' 
or something like that

remember, if you try to access a nonexistant variable, it won't give you any 
error, just return a nil value. (and fail somewhere else because of that nil 
value)
