$ is not a function - jQuery error

Question

I have the jQuery loaded fine, I\'ve quadruple-checked, though I\'m getting this error in FireBug \"$ is not a function\" and my code doesn\'t work.

Here\'s my code:

When jQuery is not present you get $ is undefined and not your message.

Did you check if you don't have a variable called $ somewhere before your code?
Inspect the value of $ in firebug to see what it is.

Slightly out of the question, but I can't resist to write a shorter code to your class assignment:

    var i = 1;
    $("ol li").each(function(){
        $(this).addClass('olli' + i++);
    });
