How to solve "syntax error at line 1 " - regex

Question

Hi I've used lex and yacc to create my own programming language syntax (sort of) , but no matter how my grammar rules are put , it gives me syntax error at the same first line.
This is my lex code of regular expressions:
%{
#include <stdio.h>
#include "y.tab.h"
%}
%option noyywrap
punct [.]
virgula [,]
numar [0-9]+
numar2 [0-9]
%%
"&librarie=>" {return INCLUDE;}
"stringuri"|"vectori"|"mape"|"matematica" {return LIBRARII;}
"intreg"|"caracter"|"string"|"natural" {return TIPVAR;}
"real" {return REAL;}
"daca" {return DACA;}
"pentru" {return PENTRU;}
"cat_timp" {return CATTIMP;}
def_variabla_globala {return VARGLOBALE;}
def_variabla_locala {return VARLOCALE;}
structura_obiect {return STRUCTURA;}
"procedura[]" {return PROCEDURA;}
start_program {return START;}
stop_program {return STOP;}
inceput_bloc_if {return INBLOCIF;}
sfarsit_bloc_if {return SFBLOCIF;}
atunci {return ATUNCI;}
altfel {return ALTFEL;}
from {return FROM;}
to {return TO;}
smaller_than {return MAIMIC;}
greater_than {return MAIMARE;}
equal_to {return EGAL;}
different_than {return DIFERIT;}
inceput_bloc_for {return INBLOCFOR;}
sfarsit_bloc_for {return SFBLOCFOR;}
inceput_bloc_cat_timp {return INBLOCCATTIMP;}
sfarsit_bloc_cat_timp {return SFBLOCCATTIMP;}
executa {return EXECUTA;}
suma {return SUM;}
invers {return INV;}
oglindit {return OGL;}
"<-" {return ASIGNARE;}
[a-zA-Z][a-zA-Z0-9]* {return ID;REJECT;}
{numar} {return NUMAR;REJECT;}
[0-9]{punct}{numar} {return NUMARREAL;}
{numar}|({virgula}{numar})* {return VECTASIGN;}
({numar2}{punct}{numar})|({virgula}({numar2}{punct}{numar}))* {return VECTASIGNREAL;}
[a-zA-Z][a-zA-Z ]* {return CUVANT;REJECT;}
afisare {return AFISARE;}
[ \t] ;
\n {yylineno++;}
. {return yytext[0];}
%%
I used REJECT at those 2 regex , because it gave me a warning , several of my rules were having conflicts with each other.
My grammar rules :
%{
#include <stdio.h>
extern FILE* yyin;
extern char* yytext;
extern int yylineno;
%}
%token INCLUDE LIBRARII ID TIPVAR CUVCHEIE REAL NUMARREAL FROM TO VECTASIGNREAL VARGLOBALE VARLOCALE VECTASIGN STRUCTURA PROCEDURA START STOP DACA PENTRU CATTIMP INBLOCIF SFBLOCIF ATUNCI ALTFEL MAIMIC MAIMARE EGAL DIFERIT INBLOCFOR SFBLOCFOR INBLOCCATTIMP SFBLOCCATTIMP EXECUTA SUM INV OGL ASIGNARE NUMAR CUVANT AFISARE

int yyerror(char * s){
printf("error: %s line:%d\n",s,yylineno);
}
int main(int argc, char** argv){
yyin=fopen(argv[1],"r");
yyparse();
}
And this is the file that I test with , and it should return that the program has a correct syntax.

I don't know where it could be wrong , is because of the lexical rules , are they interfering with each other?
Thank you.
EDIT
error mesage : error: syntax error at line:1
The exact problem is that the parser sees a non valid rule at my "&librarie=>stringuri" declaration , in my file. (line 1)
