How do I fix 'W001 Unknown Global *blank*' Errors?
Hello, I was starting to learn how to script in my Roblox game and after fixing all the syntax errors I got onto trying to fix the Unknown global errors but cannot figure out how to fix them.
1 | local ModuleScript = {} |
2 | mt = getrawmetatable(game) |
3 | make_writeable(mt) |
4 | local old = mt.__namecall |
5 |
6 | mt.__namecall = newcclosure(function (self,...) |
7 | local args = {...} |
^^^ Thats all the code that has caused this error.

Usually, the error leads to unknown variable names or function calls the script doesn't recognize. Take these examples:
variable typo
1 | local food = 100 --full hunger!! |
2 |
3 | if fod == 100 then --fod is not defined and so it leads to the W001 unknown global error |
4 | print("not hungry.") |
5 | end |
function call typo
01 | local function Eat() |
02 | food += 15 |
03 | end |
04 |
05 | script.Parent.Activated:Connect(function() |
06 | if food == 100 then |
07 | return false |
08 | elseif food > 100 then |
09 | food = 100 |
10 | return false |
11 | elseif food < 100 then |
12 | Et() --Et() isn't defined so it leads to the W001 unknown global error |
13 | end |
14 | end) |
Make sure to look through your scripts for typos, but also incorrect function calls. In this case you've probably typed in a function that is incorrect.
