if showlist is not checked a textfield appears ( htmlnick ) and when you click submit if that field is empty an alert error apperas.
When you check showlist a select field appears and a checkbox to_all ( htmllist ) the chk_form function shold check when submit is click if someone is selected from that list or the to_all is checkd.

This doesn't work. Any ideea why ?
