Easier: just delete them all for that item, and write back the ones that ARE checked.

Make a group of hidden input fields called unCheckList with the id of all the records in the resultset, and a group of checkboxes called checkedList, also with the id's. <@rows> <input type=hidden name="unCheckList" value=yourIDColumn> <input type=hidden name="checkedList" value=yourIDColumn> </@rows> Then create an array of all the id's in the unCheckedList that are not in the checkedList. <@assign local$unCheckArray <@arg unCheckList type=array>> <@assign local$checkedArray <@arg checkedList type=array>> <@assign local$unCheckList <@filter array=local$unCheckArray expr="!(@@checkedList contains #1)">> Then use the unCheckList array with an IS IN operator on your update action. You'll need to check for empty arrays, because Tango still chokes on those.

Pretty cool! So, speaking of un-checks...got any suggestions? I'll be trying to set up some of those later this afternoon.
