Lists passing from REQUEST to REQUEST is a bit trickier. You have to
rebuild the list again. try (untested):

<dtml-in del_list>
 <input type=hidden name=del_list:list value="<dtml-var sequence-item>">
</dtml-in>

(and as a side effect you can give the user the possibility to check any
single file, which he had choosen)
