[SWFObject] external interface problems

[Maurice Moore]

hmm.. now i remember.

i couldn't work out how to return something to flash when i use geturl 
to invoke the cookie 'get' function. at the moment it returns the value but

return getURL("javascrtipt:getCookie('page');");

wasnt returning anything.

any ideas?
