Im kind of new to this forum so I do my best…
Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
at Error$/throwError()
at flash.net::URLVariables/decode()
at flash.net::URLVariables()
at flash.net::URLLoader/onComplete()

I’m not where error exactly the error happen so I post the whole thing.
As far I know bottom code that relate to send_loc.php works fine, get_loc.php is having a problem. The output from get_loc.php is

&x=400&y=375&o=1
