[antlr-interest] What does this error mean in english?

"mismatched tree node: DOCUMENT expecting DOCUMENT"


I'm not having very good luck trying to do simple things apparently.

My ToStringTree:


    (DOCUMENT (PRINT 'variable'))


My tree grammar:


  document

: ^(DOCUMENT statement*)

;

  statement

: ^(PRINT LITERAL)

;
