SHOPS AND EQUIPMENT STATS

I have a bit of an odd issue, and I need some help figuring it out.

Long story short - I would like the stat window in the shops to NOT display the increase or decrease in attack\defense, but am unsure how to do this.

Short Story Long - The way I calculate stats is somewhat complex. There are 20 classes, and each class has the same "Base" stats. (Example. 15 HP at level 1). Each class then modifies those stats using Parameters (Example. Fighters get 115% HP, Wizards get 85% HP). Then, I further this by having the actors also have stat bonuses using parameters (Example. "Raid" (A natural fighter) gains 115% to HP, and "Shanidar" (A natural Wizard) gains 102% to HP). These Percentages combine to get the stats I want for person and classes.

However, those percentages carry over to equipment. So, a longsword that I gave +15 attack to, will be +17 for a fighter, +12 for a wizard, +13 for a different wizard, and so on.

I'm using a script by Prexus (Static Parameter Change). It uses note-tags and the attack parameter percentages don't affect it. All is well and good, so I assign all weapon and armor stats using note-tags.

But when I head into a shop, all weapons and armor give all my actors an increase of "0". There is no point in having it there.

Please let me know if I can get you more information. Thanks ahead of time for your help!

That might not be a bad idea. Currently, I have removed the optimization from the window. If everything pans out, people will be equiping items that have more use for them, as opposed to what has the highest attack anyways.

Still at a loss on how to handle the shop though...
