cannot do combine postage discount , unable to enter less than 0-any way round?

I am unable to give buyer post discount because anything I enter comes back with must be less than 0 any way round?

I have no idea what you are doing but to reduce the postage charge, you have to enter te REDUCTION in DISCOUNT, then preview the invoice to see that the total  is correct, before sending.

When you combine an invoice for two items the postage appears as the two added together. It is no longer possible to edit that figure, so you use discount, which then gets deducted.

my point is that when I enter the discount I get ther error message must be less than 0 Discount Charge - £ 3.00 Invalid discount amount. Please enter a discount less than £0.00 (postage + sales tax).

If item was freepost, you can't combine P&P, how can you reduce 0 (Zero).
