Re: Gui Question

Hi,
I have posted my code for the interface if anyone can help. I have to
create an interface for employees pay. I think i need to create an
instance of the object (object names are Employee, SalariedEmployee,
CommissionEmployee and BasePlusCommission)for each type of employee but
not sure.
