Error: 'asEntity' and 'asItem' is Not Declared

[Kyle]

Okay, so I updated my map, and it works nicely, except I'm trying to get a sound to play when you collide with an area. It says, "(2,1):ERR :Unexpected token '{' "

I don't know what "(2,1)" means and also I don't know what "{" I should remove...
