Above is my code block ^^^^

Here is where the error is happening: local previousStage = folder.Stages.Value.
I even added a print statement before it, but its not printing at allā€¦?

I really need help with this, thanks :slight_smile:

Thereā€™s something in your conditional statement thatā€™s setting the value of Stages to nil (which is causing an error because nil is not a numerical value)

if difference < 2 or previousStage == 0 then
   folder.Stages.Value = stage

Can you try adding print(stage) and see what it outputs?

if success then
				print(stage)
				local folder = sss:FindFirstChild(folderName)
				local a = tostring(folder.Stages.Value)
				print("text " .. a)
				local previousStage = folder.Stages.Value
				local difference = stage - previousStage

I added a print(stage) there and it outputs ā€˜1ā€™.
(Also its still not printing this print statement before the error, which is weird.)

Attempted to index ā€˜nilā€™ means that it couldnā€™t find a object named stages or an object with the property(or a child) called Value this could be a couple things

local success, folderName = getPlrFolder(player)

Maybe this isnā€™t returning a foldername*
You donā€™t seem to have a Debounce so this might be whats wrong

if difference < 2 or previousStage == 0 then
	folder.Stages.Value = stage

You code will run for each part that touches it so basically if UpperArm touches it, it will run.
if LowerTorso Touches it, it will run etc etc

Edit: Attempt to index ā€˜nilā€™ should also come with what you tried to index it with so the error should say something like this
Attempt to index ā€˜nilā€™ with Value
or
Attempt to index ā€˜nilā€™ with ā€˜Stagesā€™

Then ā€œStagesā€ is not an Object in the folder try loading the game then checking the folder in explorer

Ah thanks, I tried to check what path it was aiming for and it was trying to find the folder directly in SSS rather than inside its location of PlayerInformation.

local folder = sss:FindFirstChild(folderName)

this was the root of the error ^ Thanks for the help :smiley:
