Not surprisingly, because that is what you have set as the value for asong
in the iframe link. If you want to pass a value contained in a variable, you
should use the variable, not a string. Look closely at what you are doing
when calling the iframe.

<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>
