stray /302 error

I copy pasted a set of codes from a website and it keeps on showing me the /302 error. how do I fix it.

I can't recreate your error (this doesn't seem to be your full code) but there are many more issues you will be dealing with once you've sorted that one out.

You should know that not all sketches copy and paste perfectly as some characters may get replaced due to font types and other markup routines used on web sites and forums.

This forum is the same so I would politely suggest you learn to use the code tags provided for that purpose ( </> )

Your problem does sound like a stray character was copied form wherever you got your sketch.
I am not going to CP it to try it for you as it is not on code tags and who knows how much chasing of my tail would be involved.

Your code has all these functions called out

  Rotate_Right ();
  long_beat ();
  Spin_Left ();
  Spin_Right ();
  medium_beat ();
  zigzag_Forward ();
  zigzag_Backward ();
  Turn_Left ();
  Turn_Right ();
  fast_beat ();
  Move_Forward ();
  Move_Backward ();
  Rotate_Left ();

Then there are three fast_beat() functions, you can only have 1.
And only code for 8 of the 13 funtions that are called.
