How do you unlock the door above the eyeglass store on spy island

you go inside and ask for an eye test. when he points to a symbol click on the opposite for instance if he points to the "M" click on the "W". then he will say "i see director d sent you" or something like that (if you don't know who director d is then you need to go into the big main building with all the spys standing outside and jump to the top and talk to the guy by the computer) then go outside and climb up to the door and it will be unlocked.
