I was designing a new map and all of the sudden I froze up I checked my sever and it said "Run-time error '9' Subscript out of range." I then restarted my server but I had the same error right away, what is wrong?

Ok so i got that to work but it doesn't pull up the shop though it just makes my shopkeeper talk so how can I make it pull up a shopping menu?

So how would you talk to a shopkeeper? because everytime I press control he doesn't say anything?

I have looked everywhere and I still don't know all of the controls to Eclipse Origin, so can someone list them for me because I plan on publishing my game pretty soon and I need to list the controls. Example: Attacking,Using things,Gathering Resources… ect.
