Attempt to index global 'pairs' (a function value)

Help and Feedback Scripting Support
#1 
for i, part in pairs:GetChildren() do
   currentAmount = currentAmount + 1
end

When I execute this code in a script inside workspace, I get the next error in the console:
Workspace.Script:4: attempt to index global ‘pairs’ (a function value)
What does it mean and how can I solve it?

pairs is a global iterator function. In your example you are treating it like an Instance. You use it like this:

for key, value in pairs(tbl) do

end

-- to loop directly through an Instance's children..
for i, child in pairs(Instance:GetChildren()) do

end

attempt to call method 'GetChildren' (a nil value)
Now it gives another error…

:GetChildren is a method of instances. An instance are things like parts, models, scripts and other stuff. So GetChildren cannot be used on pairs. Your code should look something like:

for i, part in pairs(theNameOfTheModel:GetChildren()) do
   currentAmount = currentAmount + 1
end

This would go through every child inside of the model you have defined. You should also post your updated code so we could see what you’re doing.

You need to replace Instance with your reference. My code is an example.

Just specifying what iNoobe_yt wanted to understand what’s wrong

With the pairs, you can’t do:

pairs:GetChildren()

Pairs isn’t an object and it wouldn’t specify what object as it would result in an error.

Try doing…

pairs(OBJECT:GetChildren())
-- OBJECT is the object you are currently dealing with, like:
-- [[ pairs(game.Workspace:GetChildren()) ]]
