There were a variety of issues.
1) You had both using a trigger of any form submit. Of course you only want them updated when the button was pressed associated with the action, so I updated that to use the button press event and named the buttons to be easily identified.
2) You had your update code in an IF statement.
3) Your cancel value field was set to get the value from the KillID form element, and you want it from the kill_value form element
4) You had your id column type set to integer, but it is actually a text field in the database with zeros in the front. Setting it to integer removed the zero placeholders and made it not find the value to update.
Fixing these issues made your page work properly.
