Script cross-browser issue

http://pastie.org/576836

Everything works fine in Firefox and Opera.

I don’t know why, but IE6 & IE7 and Chrome just ignore these strings:

$(’#cat1 option’).bind(“click”, function(){current_cat1 = $(this).attr (‘value’); call_cats();});

$(’#cat2 option’).bind(“click”, function(){current_cat2 = $(this).attr (‘value’); call_cats();});

$(’#cat3 option’).bind(“click”, function(){current_cat3 = $(this).attr (‘value’); call_cats();});

$(’#cat2’).html(’’);

$(’#cat3’).html(’’);

Any guess why?
