Condition types. does not display amount

Dear all,

I have maintained condition types (PR00,KF00,K007). But on the VA01 screen, total amount does not display. For example:PR00=5 eur+KF00=0,5eur =5,5eur and K007 discount for customer 10% of 5,5eur=0,55eur. Here it does not show amount 4,95eur.

What should I do?

Thanks in advance.
