Works In All Except Safari Mobile

So I’m trying to add a song to the queue with:

[CODE]
document.song.SetQTNEXTUrl(1,'<music.mp3>T<myself>’);
[/CODE]

This works perfectly on all platforms, except the one I really need it to work on: Safari Mobile(iPhone)

I keep getting this error:

[CODE]
TypeError: Result of expression ‘document.song.SetQTNEXTUrl’ [undefined] is not a function.
[/CODE]

Anyone have a clue as to what is wrong?

Also in #JavaScript _↴
