$2 not a string

[Jim Michaels]

in the .y file,
                                    |
                        ZERO T_SECTION 
                         { SyntaxNode t; t.ystype=0; t.enum_ystype=STRVAL; 
t.datum.strval=_strdup($2); deque_put_back(t); }
                                  |


                        | T__CELTYPE code6
                         { SyntaxNode t; t.ystype=9; t.enum_ystype=STRVAL; 
t.datum.strval=_strdup($1); deque_put_back(&t); }

                        | T__CELWEIGHT code370
                         { SyntaxNode t; t.ystype=9; t.enum_ystype=STRVAL; 
t.datum.strval=_strdup($1); deque_put_back(&t); }

                        | T__CEPSNID code390
                         { SyntaxNode t; t.ystype=9; t.enum_ystype=STRVAL; 
t.datum.strval=_strdup($1); deque_put_back(&t); }

I have tried this with yylval and with $2.  I get the same results.  I am using 
bison 2.1 (sorry, it's the latest version available for my platform).

apparently what gets put in as a datum is a null the first time (here).
the rest of the times I use $2 I get an empty string or a crash when I try to 
print the string.  it works until the 10th item.

what I want is the string value from flex.
help
