I also did try changing the “Script.Parent[“DialogueGui”]” to “Script.Parent.DialogueGui” but that still didnt fix it.
This is how it is in Studio

On the client you should always use parent:WaitForChild(). This will yield until the child is found. Your script is probably running before the GUI exists.

I see, I’m not that good at scripting, my friend who does most of the scripting but he’s busy and I needed to fix that script. That fixed it, thank you so much!
