Hello! I have a problem. I have wrote this script: 
  
addCommandHandler ( "wajsic", 
   function (thePlayer) 
        local accountname = getAccountName ( getPlayerAccount ( thePlayer ) ) 
        if isObjectInACLGroup ( "user." .. accountname, aclGetGroup ( "admin" ) ) then 
        setElementPosition( thePlayer, 1257.8564453125, -775.72027587891, 92.03125 ) 
        end 
    end 
) 
  
 
Problem is that I get an error: 
\script.lua: attempt to concatenate global 'accountname' (a nil value) 
What could it be? 
Thanks!
