Are you not able to return a value in a function to an event function call?
The gist of the program I've written is for a user to touch a part, and then create a variable called "owner" that is equal to their player ID. Right now, I'm just trying to print the owner/UserID. Except the output keeps displaying "Connection - Server - Script:17" before I even touch the part. Which is why I'm wondering, is the "playerId" variable not allowed to be returned to the event function call? And if so, how can I create a variable outside the scope of a function equal to a variable inside the scope of the function? (And also, if anybody knows, what "Connection - Server - Script:17" means?)
local Players = game:GetService("Players")
local touch2claim = script.Parent.touch2claim
local function claim(otherPart)
local partParent = otherPart.Parent
local humanoid = partParent:FindFirstChild("Humanoid")
if humanoid then
local character = humanoid.Parent
local player = Players:GetPlayerFromCharacter(character)
local playerId = player.UserId
return playerId
end
end
local owner = touch2claim.Touched:Connect(claim)
print(owner)
I'm fairly new to programming on Roblox. So any help is appreciated!
EDIT: I think I may have solved it. Here is my new code:
local Players = game:GetService("Players")
local touch2claim = script.Parent.touch2claim
local owner = nil
local otherPart = touch2claim.Touched:Wait()
local partParent = otherPart.Parent
local humanoid = partParent:FindFirstChild("Humanoid")
if humanoid then
local character = humanoid.Parent
local player = Players:GetPlayerFromCharacter(character)
local playerId = player.UserId
owner = playerId
end
print(owner)
Feedback is appreciated!

The variable owner is set to the connection value of the event Touched. This is because connections have a value that can be assigned to a variable. When you assign a connection to a variable, you can disconnect the function which was previously connected to the event.
An example of disconnecting a connection would be:
local connection = game.Players.PlayerAdded:Connect(function() -- this is where the connection is created
-- logic code
end)
--...
connection:disconnect()
-- Now that the event is disconnected, when the event is fired the function that connected to the function will not run
The value returned in the claim function will not be passed to the owner value.
I would recommend doing something like this:
local Players = game:GetService("Players")
local touch2claim = script.Parent.touch2claim
local owner = nil -- initialization
local function claim(otherPart)
local partParent = otherPart.Parent
local humanoid = partParent:FindFirstChild("Humanoid")
if humanoid then
local character = humanoid.Parent
local player = Players:GetPlayerFromCharacter(character)
local playerId = player.UserId
owner = playerId
end
end
touch2claim.Touched:Connect(claim)
print(owner)

EDIT
I forgot to mention why you are getting the output that you are getting.
That is the connection which is being outputted as a string. The reason that it is outputting before you touch a part is because it is not really 'linked' to the connection, rather it is the connection. Due to it being the connection, it does not fire when the event is fired, but rather after the connection is created.

try
local Players = game:GetService("Players")
local touch2claim = script.Parent.touch2claim
touch2claim.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") then
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
return print(player.UserId)
end
end)
if it doesn't work dm me on
