Script Fixed, but Doesn't Function Like I want it To Do?

This script was fixed by Zafirua and surprisingly it didn't work. This time I added the Output, along with the picture of the studio of what I have on my Workspace, and the script fixed by Zafirua, which I want to say thank you so much!

-- Try script.Parent:WaitForChild("ClickDetector").MouseClick:Connect(On_Clicked);
-- If it errors, or not work. It means, clickdetector is being called too early. Try fixing it using a wait, find, or any other useful ones.

Should you try?
