Trying to sell a Level 80 Paladin Character that I have on the website and everytime I try and set the coins to 40 or 50 it keeps setting it to 118 almost like a typo correction thing.

Belt of the Lonely Noble with Eternal Belt Buckle and 3 Gems +12 Intellect and +10 Spell Power
Leggings of Dubious Charm with 3 Gems +12 Intellect and 10+ Spell Power and Leg Enchant +50 Spell Power +30 Stamina

Please help I'm simply trying to sell this character for less than 118 coins and it won't let me post on the trade block on the website for any less than this.

There's nothing to help you with, you won't be able to put it for sale for less. Trade has an enforced minimum price, based on equipment, inventory, etc.
You can pick the option to sell the character without inventory, delete some items or accept the minimum.
