keeping checkboxes checked in form

I have this form:
[url]http://www.mikeglaz.com/606club/join.php#personality[/url]

When the user submits the form and there are some errors on the form (i.e. the form doesn’t submit but prints errors to the user, like blank fields) I want the form to remember all the fields. I’ve been using the $_POST variable to remember the state of the filled in fields. But I don’t know how to do an array of checkboxes. Right now I have 22 checkboxes and and I’m checking each $_POST[‘abc’][index]. But there can be a variable number of indices from 0 to 21. Does anyone know of a solution?

here’s my code:

[CODE]
<a name=”personality”><p class=”minusMargin”><b>Describe your personality:</b></a>
<table cellspacing=”5″ border=”0″ class=”personality”>
