[flexcoders] Problem with post

[Guillermo Villasana]

Is there any reason why if i send with method post, one variable will 
not be sent ?

var params:URLVariables=new URLVariables();
var myservice:HTTPService=new HTTPService();

params.var1=event.values[0];
params.var2=event.values[1];
params.var3=event.values[2];

myservice.method="post";
myservice.url.....etc

myservice.send(params);

the odd things is that var1 no matter where I put it, is not sent, but 
if I just change .method="post" to .method="get"
then everything is sent correctly...
any thoughts?
