I set it up to give you $ 1,500 for the fish. Server.lua refers to an error on line 50
local price = itemAmount * math.random (Config.SellPrice)

Scrip Error: @loffe_fishing/server/server.lua:50: attempt to call a number value (loacal 'itemAmount')

Hi, just to let you know there is a syntax error in your sql file.
You are closing it with a , then a ; and the , needs to be removed
Correct sql is:

INSERT INTO items (name, label, limit) VALUES
('lfish', 'Fish', -1),
('lrod', 'Fishing rod', 1),
('lbait', 'Fishing bait', -1),
('lUbait', 'Ultra Fishing Bait', -1),
('lEbait', 'Extreme Fishing Bait', -1)
