Discount doesn't work

I use the basic edition of Hikashop and today I tried to activate a discount, but it doesn't work. I've added the discount into the Discount tab and activated it. But when I do a test, the discount is not of the totalprice when I buy something.
Do I have to configurate something else too ?

Could you do a screenshot of your discount ?
That would help us understand what problem you have.

This topic can be closed. It does work. I made a mistake in the configuration. Sorry for this inconvenience.
