    Ive created a discount voucher for 7%
    the products are 220.22
    tax is 20% = 40.34 ????

    Discount taken off for 7% is 18.50 ?????

    what has happened is it has added 220.22 + 20% = 264.26 -7%

    what SHOULD happen is 220.22 - 7% THEN add 20% tax.

    Anyone know how to solve this?

    you want to use discount before tax option. Caution: there will likely be problems with it and you would have to update your code to get it working correctly. I wrote a blog on it a while ago for virtuemart 1.1.4, but some of it has been fixed:

    Thats already switched on so the calculations are all incorrect.

    Its still taking discount after tax then recalculating the tax amount.

    just did some testing, I get the same results whether using AwoCoupon or Virtuemart coupon system. It obviously still has problems. At the very least, this solution was not implemented:

    Used your code and this is working fine.

    SO for everyone else in 1.1.8 virtuemart you still need to implement the code fix.


    Works great now many thanks
