if (ind==0) backwards = false;
if (backwards) --ind ;
else ++ind;


gr.setColor(getBackground());
gr.drawLine(60, 40, hor[ind], vert[ind]);
gr.fillOval(cHor[ind], vert[ind],x, y);


gr.setColor(Color.BLACK);

Can you please explain what exactly you want to do?
The link you have provided is not working.
Please elaborate what you want to do with your applet?

I want the app to run like a yoyo by going down a string and up a string without having to reset the downward motion to 0 at the index to get it back to the top.

Daren in the above given code I suppose you have forgot to declare the colour variable that you needs to declare, when you will declare that you will be able to access the the colour code in your program:

Here i will give you an example about how to declare it.

     Color redColor;
     Color weirdColor;
     Color bgColor;

// Standard colors can be named like this
          redColor = Color.red;

  // lesser known colors can be made with R(ed)G(reen)B(lue).
          weirdColor = new Color(60,60,122);

          bgColor = Color.blue;

my colors work fine i need it to go backwards.
