The only thing that can be going wrong is that the ID is getting misread when looping through an array with a single value. It is always reading the ID of the first row regardless which checkbox was actually checked.
You'll need to do some debugging to figure exactly why that is happening but I'd start with looking at the POST variables going to the update script. That should show you the way forward.
