Ok. The categories are coming from checkboxes, e.g.:
<input type="checkbox" name="categories[]" value="1" />Accountant<br />
Which then are handled by a $cgi class dealy and handed to the
$_SESSION['categories'] variable before being forwarded to the next
step. I was thinking that the problem might be with the $cgi object, but
when I print_r($_SESSION['categories']) it shows the contents of the
array.
Anyways, I did the print ":::{$_SESSION['categories']}:::"; and got
:::Array:::
Hmph
