I think you mean you want to pass null as an argument to the function you are calling.

Remove the quotes around the null, like this:

<a href="javascript:void(0);" onclick="javascript:chooseClassGroup('G_FREE', null, 'FREE', 'Free Stuff');">Free Stuff</a>

and by the way you can simplify your whole link:

<a href="#" onclick="chooseClassGroup('G_FREE', null, 'FREE', 'Free Stuff');">Free Stuff</a>
