Why does nothing happen after the remote is fired?

ModuleScript(Child of the Script)

local ranks = {"President", 
"Assistant Manager", 
"Vice President", 
"Corporate Officer",
"General Manager", 
"Supervisor", 
"Intern", 
"Head Team Member",
"Professional Team Member",
"Senior Team Member",
"Team Member",
"Junior Team Member",
"Trainee",
"Business Partner",
"Former Executive",
"Gold Customer",
"Premium Customer",
"Customer"}
return ranks

The gui doesn't show up above the players head, there are no errors in the output and the remote has fired correctly.
