I tried this (I changed the location to where the value was) and it didn’t give me a message in outbox. I’m super confused right now. I tried looking at its properties after clicking, but nothing happened, it stayed at zero (the default, which I haven’t changed)
What is the script.Parent referring to?
Can you provide a picture of the explorer?
using the tostring() function.
One thing that might be happening is you are not referring to the property value of the Instance IntValue but rather the Instance itself and trying to increment it by 1 which is most likely in this case.
