Problems with execute immediate

Question

HELLO :
How can I execute a procedure (with input , output parameters ) , in another schema??
I have the following code :
V_SENTENCIA:= 'begin '||v_schema_name|| .DAR_ID('||V_CODE||',:p1); END;';
EXECUTE IMMEDIATE V_SENTENCIA INTO V_Num
and the declaration on my proc is the following :
CREATE PROCEDURE DAR_ID ( p_1 in varchar2 ,p_2 out NUMBER) IS
NUM NUMBER (5,0);
BEGIN
SELECT count (id) INTO p_2 FROM Veh WHERE (Param1=p_1)
END ;
Can anyone help me please ?

3 begin
4 select 1 into p_res from dual where p_arg = '1';
5 end;

Procedure created
SQL> set serveroutput on
SQL> declare
2 l_ret number;
3 begin
4 execute immediate 'begin pp(:p_arg, :l_ret); end;' using
