[countrygirl1970]

Hello,

I am trying to get this code to work. I am getting an error code on line 38, that I don't understand why. Can anyone help me out. the error code that I am getting is identifier expected.

percentage is an array and you do:
percentage = frequency * 60000;

Also I think you have a problem with your brackets (})

public class Assignment5 extends JApplet
{

....
....

// Multiply the frequency to 60000 to get the percentage
line 38	percentage = frequency * 60000;			
	
	public void init()
	{

I see what you were talking about. I went in and changed the names of the arrays and then added two lines to reenforce percentage and frequency. I am still getting the same error code for that line. I have all my brackets in place. Where do you see the problem at.

First of all this makes no sense:

int percentage = 0;
int frequency = 0;
percentage = frequency * 60000;

And second the above code is written were you declare variables, so you cannot put commands like this there: percentage = frequency * 60000;
This thing needs to go inside a method

Your brackets are OK, that was my mistake

Thank you, I see what you are saying and I am fixing a little at a time. I have taken that statement out. Thanks again.
