Why the _x position of textfield changed after loadVars() ---MX

I have in the asp page the values like screenx=617&screeny=-8.5&text=dsdsdsds&

And I create an new flashpage which only has a textfield(which named as screen) to receive the text from asp page and position it to the place.
myData = new LoadVars();
myData.source = “http://localhost/myweb/cart.asp”;
myData.load(myData.source,myData);
myData.onLoad = function(){
_root.screen.text= myData.text;
_root.screen._x = this.screenx;
_root.screen._y = this.screeny;
};

the result of the _y of screen seems the same as the value in asp, but not the _x value!!

Is there something related with the setting of the flashpage which make the result different? Thanks in advance and wait for your reply

try outputting

&screenx=617

instead of

screenx=617

thanks, it looks better! and now in asp page,I also have
&font=Comic Sans&color=16711680& for the textfield

how about these infos. how should I add the code so that these info can also show on the flashpage then?? THanks indeed!!!

And for the galleryimage which the user have chosen, I have &galleryimage=2& 2 is the name of the gallery image, how should I write in the flashpage to retrieve it back from the directory of /uploadedimage/ folder on the server. Or is it better to save the directory than the name of it in the database???
