Can't understand this module error?
I've looked at this over and over, and can't figure out what's going wrong
ServerScript
game:GetService('Players').PlayerAdded:connect(function(player)
local api = require(script.Parent.Data)
api:CheckGroups(player)
end)
ModuleScript
function module.CheckGroups(player)
print(player.Name)
end
The modulescript only prints 'nil'
When I try to use player:IsInGroup() in the module script it returns an error.
Thanks in advance for the help.

Your function is not designed as a method
When you use : as the accessor for a function, it is being accessed as a method. Methods are special in that they tell the function where they came from when they're called.
In your code, you write this as your function
function module.CheckGroups(player)
print(player.Name)
end
Which means that when you later called api:CheckGroups(player), you actually called api.CheckGroups(api, player). As module (api) has no entry for Name, it printed nil. The solution is either to do
api.CheckGroups(player)
Or alternatively to declare the function explicitly as a method as so
function module:CheckGroups(player)
print(player.Name)
end
Still not sure? When you call a method, it calls the function with the source as the first argument. It's syntactic sugar for OOP-style methods.
