Error Handling for a locate

[DavidBrown6]

Hi,

I am doing a simple locate and was wondering how to show an error (with javascript) whenever the server is unreachable. Debugging in chrome with a false URL returns the error:
GET http://gis.hamiltoncounty.in.gov/ArcGIS/rest/services/UberLocator_10/GeocodeServer32432432/findAddre... 404 (Not Found)

It has been difficult to isolate where this error is being generated from. Any help would be appreciated.

Thanks
