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:

<script type="text/javascript">
    $("ol li:nth-child(1)").addClass('olli1');
    $("ol li:nth-child(2)").addClass("olli2");
    $("ol li:nth-child(3)").addClass("olli3");
    $("ol li:nth-child(4)").addClass("olli4");
    $("ol li:nth-child(5)").addClass("olli5");
    $("ol li:nth-child(6)").addClass("olli6");
    $("ol li:nth-child(7)").addClass("olli7");
    $("ol li:nth-child(8)").addClass("olli8");
    $("ol li:nth-child(9)").addClass("olli9");
    $("ol li:nth-child(10)").addClass("olli10");
    $("ol li:nth-child(11)").addClass("olli11");
    $("ol li:nth-child(12)").addClass("olli12");
    $("ol li:nth-child(13)").addClass("olli13");
    $("ol li:nth-child(14)").addClass("olli14");
    $("ol li:nth-child(15)").addClass("olli15");
    $("ol li:nth-child(16)").addClass("olli16");
    $("ol li:nth-child(17)").addClass("olli17");
    $("ol li:nth-child(18)").addClass("olli18");
    $("ol li:nth-child(19)").addClass("olli19");
    $("ol li:nth-child(20)").addClass("olli20"); 
</script>

There are quite lots of answer based on situation.

1) Try to replace '$' with "jQuery"

2) Check that code you are executed are always below the main jquery script.

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){

});
</script>

3) Pass $ into the function and add "jQuery" as a main function like below.

<script type="text/javascript">
jQuery(document).ready(function($){

});
</script>

I believe using $ alone is now deprecated in the new version of jQuery. Use below syntax instead:

jQuery(function($) {
//magic here
})
