LoadVars.load() syntax

Is there a way of making a normal loadVars.load load a url depending on a variable you set in the swf?

var reciever = new LoadVars();
loadurl = “test_onload_3.cfm?propertyID=”+MY_VARIABLE_GOES_HERE;
reciever.load(loadurl);

so that I can set my variable and then load the variables with the propertyID that I choose in the swf???
