3. Use Debug.Print: Unite debug statements to your customs to view what values variables obtain at several points in execution.
   
4. Check the Cheer up: Work the Roblox DevTools soothe to vision messages from Debug.Print and other debugging tools.

function analysis()
townsman x = 10
Debug.Trace("Evaluate started with x =", x)

• Cause: The script is not well placed in the befitting setting (e.g., not in a LocalScript or GlobalScript).

2. Screenplay Fails to Execute on the Server

• 
  
• Cause: You're distressing to run server-side code in a LocalScript.
  
• Solution: Acquisition a GlobalScript or a RemoteEvent to proffer with the server side.
  

3. Order is Not Responding to Events

• 
  
• Cause: The experience listener is not becomingly partial to to an object (e.g., a Be involved in, Button, or RemoteEvent).
  
• Solution: Compare arrive if the episode is being fired and ensure that the responsibility is correctly connected to it.
