Problem getting variables

Hi! hello and happy new year
I have a problem; i need to load a series of variables into a menu. seems easy, i’ve done many times. the thing is, i have to get them from an asp who asks for a parameter.
So i tried this:

loadVariables("/medidores/txtflash.asp?pkey=c0321733a51ffa323f", 0, “GET”);

but this not seems to work. So, i tried this instead:

send_data = new LoadVars();
send_data.pkey=c0321733a51e82fadc8b3f081ffa323f;
trace(send_data.pkey);
send_data.sendAndLoad(“medidores/txtflash.asp”, get_data, “POST”);

but my question is: does flash actually stores whatever is in txtflash.asp into “get_data”?

thanks, any help or light will be very appreciated
