Sorry I do not understand ;-( 4u-66 / 1u-4 ?
7 and 2 are in 1 box but 66 and 4 are for all the ribbons no ?

Total = 100% = 5u
Yellow = 80% = 4u
Red = 20% = 1u
After
Yellow = 4u - 66 = 7p
Red = 1u - 4 = 2p
Yellow = 80% = 4u
Red = 20% = 1u
After
Yellow = 4u - 66 = 7p
Red = 1u - 4 = 2p
Oh I see thanks
