HI
I can't seem to find this solution in other threads. On one of my sites, when using a discount coupon "First Order" you get 10% off. But the VAT is calculating wrong when using the coupon. I cannot see where the figure is coming from. I've tried turning tax on and off for shipping and the coupon but this is not the issue. I can't see what values its using to calculate tax.
Wrong Values:-
Sub-Total: £13.98
Discount Coupon: First Order : -£1.40
Shipping Method (Standard): £6.95
VAT 17.5%: £3.17
Total: £22.70
What it should be:-
Sub-Total: £13.98
Discount Coupon: First Order : -£1.40
Shipping Method (Standard): £6.95
VAT 17.5%: £3.42
Total: £22.95
Where is £3.17 for Tax coming from??? Its like it thinks the total to calculate tax on is less than it is. The total to calculate tax on should be £13.98 - £1.40 + £6.95 = £19.53 (17.5% of which = £3.42). BUT £3.17 is 17.5% of £18.11. So where is it getting £18.11 from??
Thanks
Laurie
