[pgrouting-users] problem with dijkstra_sp

[Radhika]

Hi ,
  When I'm running    SELECT gid, AsText(the_geom) AS the_geom FROM dijkstra_sp('road', source id,target id);
  
I receive the following error

ERROR: column reference "edge_id" is ambiguous
SQL state: 42702
Context: PL/pgSQL function "dijkstra_sp" line 12 at for over execute statement


Can any one suggest me , what should I do to remove this error and make dijkstra_sp working.


Thanks & Regards
Radhika.
