How do you buy and sell? VERY confused!

I just need a full explaination on how to buy and sell things on this server. people tell me to right and left click, but it doesn't work. also, how do you tell what the price of an item is? I'm just confused. Please help!

when you see a chest shop you do right click to buy and left click to sell the sign, if your wanting to make a chest shop place a sign above a chest and use the format.
(username) nsuth13
(amount your selling) 5
(price) 100 B:S 99
(item) torch
I hope this helps.

Thank you, but I still don't get the price thing. I just see Number:number. How exactly do you tell the exact price?

Breaking this down.
First line is the name of the vendor.
Second line is the amount of items you will receive from purchasing, or lose from selling.
The third line is tricky.

100 B:S 99

This basically means:

It costs 100 to buy (b) 5 (second line) torches (fourth line).
-or-
You can sell 5 torches for 99 coins.

And of course, the fourth line shows the item your buying.
So nsuth13 has a shop. You can buy 5 torches for 100 coins, or sell 5 torches for 99 coins.

Starting to make sense? Heres another example.


So at my shop you can buy 20 melons for 30 coins or sell 20 melons for 15 coins.


Well there you go. Hope you get it now.
