Error capitalizing employee name!!!!

Hi Gurus,

I'm receiving the following error when capitalizing the first and last name of an employee, for example from JOE DOE to Joe Doe.

Person: company resource assignments: Error applying dynamic template for Display value on object DOE, JOE - JDOE.

Error executing script 'Tmpl_PersonHasObject_YDisplayValue'.

The Specified ObjectKey was invalid.

Any ideas?  =S

Thanks,

JM
