Crystal Reports Triming

Message


     I have a field with the following value in it
 
10981000
 
I am trying to get this field on the report with the last six characters using the formula below
 
Right({Employee_job_History_SCD.Client_ID}, 6)
 
I get the following error with this code
 
A string is required here
 
Right({Employee_job_History_SCD.Client_ID}, 6)

 
The field is Client_ID(PK,Int, not null)
 
Any help would be appreciated
