This looks like your problem.. try this:
data = ${lookup mysql { MYSQL_QUERY_ALIASES }{$value}}
You'll need to do the same thing for the rest of the lookups as well.
Basically, you're saying data = "" because the lookup returns information in
$value but you're not using it. I've been burned with this before.
