ORA-00942: Table or view does not exist

Hi all,
         Im getting this "ORA-00942: Table or view does not exist" even though i have this table in my database. The following is the situation where im getting this. I have a table by name EMP_NO in schema HR. I created a public SYNONYM by name EMP_NO. When i tried to access this table, EMP_NO in another schema PAYDEPT, then im getting this error. I have also issued " GRANT ALL ON HR.EMP_NO TO PAYDEPT" but even then im getting this error. Following are the queries that i have issued to show this relationship.

SQL> select owner, object_type from dba_objects where object_name='EMP_NO';

OWNER         OBJECT_NAME                 OBJECT_TYPE
---------------    ---------------                    ------------------
PUBLIC              EMP_NO                              SYNONYM
SYSTEM            EMP_NO                              SYNONYM
PAYDEPT          EMP_NO                              SYNONYM
HR                     EMP_NO                                TABLE



SQL> select owner, synonym_name, table_owner from dba_synonyms where table_name='EMP_NO';

OWNER       SYNONYM_NAME     TABLE_OWNER
-------                   ------------           -----------
PAYDEPT       EMP_NO                          HR
 
PUBLIC           EMP_NO                         HR

SYSTEM         EMP_NO                        HR

I guess it might have given this error if i use HR.EMP_NO to refer to EMP_NO table in PAYDEPT schema. But we already have the PUBLIC SYNONYM, which by default grants all access to this particular table to all schemas in the database, so, could anybody please help me to find out as what would be the issue here.

Thanks,
Harris
