It says "NPC definition is null." When i click to the alch or the splash tab, the tab is like compressed, and when i expand the window the drop down menus don't have any options

Hi! The script has worked great for awhile, but now when i try to alch/stun, the drop down menus do not work properly. they don't show any options and I can't select anything. Would appreciate help!
