internet explorer 7 - Google Analytics and IE Browser -

Anyone can explain to me why Firefox works but not IE

  Function booking service (MyForm) {_gaq.push (('_ linkByPost', myfo, true)); Back true; } & Lt; Form id = "booking-form" action = "https://myurl.com" method = "go" onsubmit = "booking book for return (this);" & Gt; & Lt; Input type = "text" name = "whatever" /> & Lt; Input type = "submit" name = "send" /> & Lt; / Form & gt;  

Thanks!

There may be a silly question, but where does the GA code define _gaq? Head, or the body of your document?
