Using a checkbox with callback function

I have some checkboxes on my form and want to pass the checked ones to my function; I'm using this: function testadd($vars) { $s=$var['skills']; var_dump($s); } But the var_dump is returning NULL, what is the correct format to pass the checkbox array? What I will need to do is if a checkbox is checked save its name to the db as in skill['name'].. www.bitesoftware.com - software for a better lifestyle _________________________________________________________________ Be the first to hear what's new at MSN - sign up to our free newsletters! http://www.msn.co.uk/newsletters
