Divide By zero error

Hi All,I have this expression :((Fields!Number_of_Instalments.Value - 1)* Fields!Admin_Fee.Value)+ (Fields!Admin_Fee.Value / Fields!Monthly_Payment.Value * Fields!Final_Amount.Value)The issue is that where the monthly Payment is 0, it will result to #error. I want to be able to return zeros for all the monthly payment that is zero instead of #error. Thanks,E.O
