Tuco asked 'How do you change the items in the chests'

Tuco,

Q1. How do you change the items in the chests?

Find all the chests on the Containers tab, find the chest with the name that you want to modify, double-click it and you will be taken to the screen that allows you to place items in the chest - or remove them. Only do this with unique chests that you have created for your character i.e. a character that you have created and given a unique name. If you change chests that your NPCs do not own, then you risk screwing-up the system.

Q2. How do you make the merchant have money to buy your items?

Same deal as with the items in the chest. Find the trader that you have created on the NPC tab, double-click to open his inventory, then find the gold objects on the Misc tab. Click on one of the gold items and, whilst holding down the left mousebutton drag the gold into the traders items area in the lower right part of the screen.

I hope this answers your question.

Dave
