X cannot be assigned to Roblox scripting problem on Roblox.com?

I'm really bad at scripting and the script says "X cannot be assigned to." i dont know what to do and im really sad

You can't assign number values to axes individually, you must create a new Vector3. Say the erroring line in your script looks like:

workspace.Part.Position.X = 5

This won't work because you're attempting to set X to a number value, while it's a Vector. Instead this line should look like:

workspace.Part.Position = Vector3.new(5, 0, 0)

Let me know if this doesn't satisfy your question, I would be glad to try and fix it! Hope this helps!
