php vars cut off in flash getURL()

I am having problems getting my php vars to stay on my actionscript getURL commands.

here are the particulars:

i am using a actionscript #include featuring the following code:

//actionscript
reel_mc.male_14_btn.onRelease = function() {
getURL("http://www.betaspace.org/communities/index.php?site=community", "GET")
}

I am keeping the default GET method but when I click on the button I get the follwing page without my variables:

obviously this is a problem, it leads to a rather crappy looking admin page.

do I need to include a HTTP_GET_VARS in my index page?

Any thoughts?
