Can you help me?¿
I'm doing my own goto program, and it says that my argument isn't a number, when I try to compare the position in X to the X destination.



thanks.

What is the number that is within the error code?

EDIT: I might not be right but I think it is line 4,5,6

local tArgs = {...}
local xto = tArgs[1]
local yto = tArgs[2]
local zto = tArgs[3]

You might have to convert them to numbers.

local tArgs = {...}
local xto = tonumber(tArgs[1])
local yto = tonumber(tArgs[2])
local zto = tonumber(tArgs[3])

thanks a lot !

I convert them to numbers =)

Awesome :D/>/> Feel free to ask if you have any more problems. Everyone gets caught out with setting variables to numbers from an input.
