The World of Avlis

I have a Alvis Zero Mod. When I load it to test something I get errors that are from the Alvis_OnEneter script. I went to the script in the tooset and tried to compile it and the script will not compile. Can I get another Alvis_OnEnter script to replace this one? and it mentioned the d_corpse script, is that in the OnEnter script? If not I need another one of that too.
