ok I have uploaded the new test files to my development server, if I add 6 of one item to the cart the discount rule is triggered correctly

if I add two quantities of the same product type (the number after the product type is the ID that I am checking for) then the discount rule doesn't get triggered

If I add two quantities of different product types (both covered by the rule) the discount rule still isn't triggered

I am obviously missing something simple, but what ?
