In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.

Use the </> icon from the ‘reply menu’ to attach the copied sketch.

Something is looking strange :face_with_spiral_eyes: .

Not an arduino programming question!!!!

but the compiler told you the error! you have some closing .curly brackets (}) missing from your code (not wonder really, its so messy!)

While the two threads are not technical duplicates there is benefit to having a single thread.

@secret_glow, as you struggle with syntax please post here.

I did not understand?

Don't sweat it. Just carry on.
