Not that I have tested this, but....
I suspect the "submit_action" values are clobbering each other when parsed.
Try putting them in two different forms, and I am not sure if that name will work.
<form action="../item/item_manage" method="POST"> <input id="Add" name="submit[action]" type="submit" value="Add"> </form> <form action="../item/item_manage" method="POST"> <input id="Delete" name="submit[action]" type="submit" value="Delete"> </form>
