public void paint (Graphics g)

g.fillArc(200, 250, 100, 100, 100, aDegree);
g.setColor(Color.PINK);
g.fillArc(200, 250, 100, 100, 100, 216);

g.setColor(Color.MAGENTA);
g.fillArc(200, 250, 100, 100, 100, 36);

repaint();
}
}

I am trying to create an applet that takes input from the form and then turns into a pie chart. I am able to convert the strings to numbers but I can;t the arc to reconigize the varaible to set the angle at. Any Suggestions? I would greatly appreaite any help. I know the fourm won;t give me the answer but shoudl point me in the right direction.

Thanks,
Brad

The problem you are encounter is a variable scope issue.

You declared local variables in your actionPerformed() method but are trying to access them in your paint() method which is why you are getting compiling problems.
 
Don't get me started about those stupid light bulbs.
