Please help, what am I doing wrong?

/**

// 1. Acquire duration hours from user and put the value into int variable "hours"
// Recall from slides: hours = Integer.parseInt( JOptionPane.showInputDialog(...));
String userInput = JOptionPane.showInputDialog(null, "Type in your hours: ");
int hours = Integer.parseInt(userInput);


// 2. Acquire duration minutes from user and put value into int variable "minutes"
String userInput = JOptionPane.showInputDialog(null, "Type in your minutes: ");
int minutes = Integer.parseInt(userInput);

// 3. Acquire duration seconds from user and put value into int variable "seconds"
String userInput = JOptionPane.showInputDialog(null, "Type in your seconds: ");
int seconds = Integer.parseInt(userInput);

// 4. Convert from (hours, minutes, seconds) into just seconds, and store value into the variable "totalSeconds"

// 5. Print out the value of "totalSeconds". Remember to output something like "Total seconds = 10,201"

}
// end main

You need to read up on how to declare variables and how not to declare them.

You are trying to use some variables without declaring them as in this line:

totalSeconds = 0;

I wonder why you don't declare this as int when all the previous variables have been nicely declared.

In other situations you redeclare variables that have already been declared;

int hours;
//.... code deleted
int hours = Integer.parseInt(userInput); // redeclared as int here

You can't do this. Declare hours as int once, then use it without re-declaring it:

int hours;
//.... code deleted
hours = Integer.parseInt(userInput);
