awocouponPro has a problem of calculation at a discount

Hi, I use awocouponpro
vm 1.1.9 joomla 1.5.26 awocouponPro 1.5.2
My site has a problem of calculation at a discount
example, an article was € 100 with a € 5 discount should bring the total to 95 €

displays on my Cart € 94.02 :(
I already look before and after unsuccessfully VAT

an indication in the checkout_last_step amount is good

Do you have any idea website is http://www.tahitiperlesetmineraux.com

thank you

for tested on my website, coupon code newsletter5

Ok, so you are using discount after tax.

In the admin section, please go to virtuemart->admin->configuration, and make sure 'discount before tax' is unchecked. Also within AwoCoupon->configuration, make sure you have 'discount before tax' set to no. I think that will fix the problem.

Seyi Hello, I am confused
go to virtuemart-> admin-> configuration was the right solution
thank you very much

In french :
En français, le calcul des remises ne doit pas être avant les taxes, sinon le calcul de la remise est erroné.
il faut désactivé le calcul des remises avant les taxes dans la configuration de VM.
merci à seyi pour son aide.
excellent support chez Awo :)
