As You Can See The 1st box you have the selection of what service to post via,
2nd is zone as some places cost more eg scotland costs £10 more then england
3rd is bag or parcel yet again price changes eg a small bag is £5 and a parcel is £8
4th delivery service eg next day, before 1pm, before 9am
5th size eg small parcel, letter, large letter,
6th class for royal mail eg 2nd class, 1st class, SD UK 1pm, 1st class SF
7th profit (10%-100%)

is there any way i can make the 2nd, 3rd, 4th, 5th, 6th and 7th all add up depending on whats selected?
Many thanks!
