Lua [HELP] Fishing Script

[middley]

Hi, I found a fishing script here on the forum, I'm using an OTX2 engine. The script does not work, an error appears in the console as below in the picture. How to fix it?

local config = {

[Itutorial]

try changing it to

local now = false

 

[middley]

same,

attempt to index local 'now' (a boolean value)

@EDIT
I Fix it, problem is with chance math.random just delete one "0" and working finely.
Thank you Itutorial!!!
