Hi @MirriamM - to clarify the instructions left in the previous comment are for a specific state, Wisconsin. I'm in California so those instructions are not valid. In other words the options (Steps) specified in the previous comment are not available to me. 

I know how to assign a workers comp code to an employee. What I'm trying to do is edit a LIST of workers comp codes and the rates for those codes.

Just typing in a code for an employee doesn't get me all the way there unless I can see what rates are being applied per code.
