yacc/lex parser not catching certain terminals - flex-lexer

Question

I built a scanner->parser meant to catch modified Java. When testing it, I noticed that codeBlock never triggers but varDecls triggers. I'm not entirely sure why this happens.
Here is my parser
%{
#include <stdio.h>
extern int yylex(void);
void yyerror(char *s) {
fprintf(stderr, "error: %s\n", s);
}
int yywrap(){ return 1;}
%}
%token INT FLOAT STRING
%union {
int ival;
float fval;
char *sval;
int bval;
}
%token <ival> NegInt
%token <ival> Int
%token <fval> Float
%token <bval> Bool
%token <sval> ifHeader
%token <sval> thenHeader
%token <sval> elseHeader
%token <sval> forHeader
%token <sval> whileHeader
%token <sval> ID
%token <sval> BinOperator
%token <sval> BoolOperator
%token <sval> Assignment
%token <sval> Quotation
%token <sval> LBracket
%token <sval> RBracket
%token <sval> LFBracket
%token <sval> RFBracket
%token <sval> Semi
%token <sval> LABracket
%token <sval> RABracket
%token <sval> Comma
%token <sval> String

Here is my scanner:

As you can see with my print statements, I was trying to trigger my parser to print out "why doth this triggering" but instead varDecls is triggered instead.
Additionally, varDecl also triggers. Is that supposed to happen?
Help would be very appreciated. Thank you
