Help to pass a local variable from Freeradius to exec program

Hi All I am trying to pass a integer value from Free radius to exec program . I have tryed to add as a value pair using paircreate() and then added the same to the request->packet->vps using pairadd. Set the lvalue , strvalue etc and passed to the radius_exec_program from rad_accounting module. Also set the tmp->name = "Atribute-Name-Format" . Still the attribute and value is not getting printed in the exec - progrm . Any help in this regard whould really help me. Thanks and regards Shankar ganesh
