Bison lex matching error

[Sean Walton]

I am having problems with getting Bison to match this:

       Modifier module test {

The rule fragment is:

       module : ANESC_Modifier MODULE id_name

The lexer tokens are:

      ANESC_Modifier = "Modifier"
      MODULE = "module"

I get the error:

      syntax error before `module'

Any ideas?
