well I made the list: NAME="ids:list" in the checkbox line
When you hit the deletebutton a method is called.
The code for deletion is here:
<dtml-in ids>
	<dtml-call sqlDeleteClips> <-- That's the sqlmethod
</dtml-in>

What's funny is that I get an 400 error.
And I have 3 hidden fiels in the same form - normally they would be
passed as ActionList=1 etc. etc. but now they are passed as
ActionList=['1', '1', '1', '1', '1', '1', '1', '1']

Yes I know I should learn some python but I'm working against time :-)
