Is this correctly written?

I Recently just watched a 23rd august, 2022 video on scripting, in which you can see here: https://youtu.be/P2ECl-mLmvY

I tried the first scripts, in which I named the part "Redsus". Heres a photo of what I tried: https://gyazo.com/e11a1a9fe0c7c377c5185836f3db49ce

and for some reason, a part does not appear as shown in this photo https://gyazo.com/89aa86969d7a462c6c33f0e724041911 (Sorry that I am using gyazo, snipping tool isnt working)

How do I solve this then?

Try TheDevKing's tutorials. They are super helpful and they work normally, thats how I am learning to script and they are super helpful!
