[jQuery] Why doesn't work in IE ?

[jQuery] Why doesn't work in IE ?


This line crashes all my jQuery scripts in IE only:
$("input[@name=breakfast]").var = state;
Part of my code:
var state = $("input[@name=orderBreakfast2]:checked").val();
$("input[@name=breakfast]").var = state;
I want to set value of hidden input named "breakfast".
Please explain me why.
