Ambiguous recognition of the tested object

Hi,

 when Iam trying to run my recorded keyword test Iam facing with this error:- Ambiguous recognition of the tested object. and object does not exist.

  ( Iam trying to click on a  IE8 browser popup window radio button object.)



Additional Information:-  Tested object:
Sys.Process("iexplore").IEFrame(0)Tested object:

Sys.Process("iexplore").IEFrame(0)



In namemapping each and every object is recorded perfect but when Iam trying to highlight that particular parent object

Iam getting this error:- The underlying object does not exist.



When Iam trying to click on "show in object browser" option in nameapping Iam getting error -please find the attachment.



Please let me know how to overcome from this.



Thanks,

Narender
