Bukkit

What steps will reproduce the problem?
1. Be using this plugin on Spout
2. Have 2 or more upgrades available
3. Purchase an upgrade that skips a lower size (ex: 27 instead of buying 18)
4. You then don't pay 18's price

What is the expected output? What do you see instead?
The price needs to add up. If all sizes were 1000 each, buying 27 instead of 18 should cost 2000, but it costs 1000.

What version of the product are you using?
Backpack b129, CB/Spout 1.5.2

Do you have an error log of what happened?
No

Please provide any additional information below.
What was fixed in b129 was the prices adding up correctly. It now shows what it should based on how the config was set, which was one of the problems I submitted before. Now, the 2nd, and larger, problem that I filed in that previous ticket for is still causing problems. Hope to see a fix soon! Thanks!

EDIT: Needs to either force 1 upgrade at a time or just add up skipped sizes.
