Why won't the else statement in my while loop execute when the conditions in the if statement aren't met?

I'm making a game called 'Game of Nim' in Netbeans. Basically, a random amount of stones between 15-30 is generated and a computer and a player take turns taking 1-3 stones until there are none left. The player to take the last stones loses. I'm coding this in a jframe form. I want to make sure the player doesn't enter a number bigger than 3, less than 1 and bigger than the total stones, so I made a while loop with an if statement for the input that meets the requirements and an else statement if they aren't met. My problem is that when a player does enter numbers that shouldn't be entered, no error message appears and the game continues as normal. Here is where I think the problem is:

    public int playerInput(){
        // Getting the user input and converting it into an integer
        int userIn = Integer.parseInt(txtIn.getText());
        //
        boolean input = false;

        // Do this while the input isn't between 1-3 and higher than the total amount of rocks
        while(!input){
            //
            if (userIn < 3 || userIn > 1 || userIn < totalStone){
                //
                input = true;                                      
            }
                //
                else{
                    // Output an error message
                    txtaOut.setText(txtaOut.getText() +"\nEnter a number between 1 - 3 and less than the amount of stones left.");
                }   
        }
        // return the amount of rocks the user takes
        return userIn;              
}

Here is most of the code for the game (I am going to use the random slashes for commenting):

    public void computerMove() {      
    // Generating a number for the computer's move
    int comIn = (int)(Math.random() * 2) + 1;            

    // If number generated is bigger than the total stones,
    if (comIn > totalStone){           
        // Get the difference between the total and the random number
        int totalComDiff = Math.abs(totalStone - comIn);
        // Subtract the difference from the random number
        comIn -= totalComDiff;
        // Substract the rocks taken from the total
        totalStone -= comIn;
        // Display a message of the rocks taken and the rocks left
        txtaOut.setText(txtaOut.getText() +"\nThe computer picked up " +comIn +" stone(s). There are " +totalStone +" stones left.");
        }
            // Otherwise, if the random number is smaller than the total,
            else if (comIn < totalStone){
                // Substract the rocks taken from the total
                totalStone -= comIn;
                // Display a message of the rocks taken and the rocks left
                txtaOut.setText(txtaOut.getText() +"\nThe computer picked up " +comIn +" stone(s). There are " +totalStone +" stones left.");

            }
             // If the total equals amount the computer takes,
            else if (totalStone == comIn){                    
                // Substract the rocks taken from the total
                totalStone -= comIn;
                // Display a message of the rocks taken and the rocks left
                txtaOut.setText(txtaOut.getText() +"\nThe computer picked up " +comIn +" stone(s). There are " +totalStone +" stones left.");          
                // Display a message that says the player wins
                txtaOut.setText(txtaOut.getText() +"\nThere are no more stones left. The player wins!");
            }            

            // Otherwise, if the amount of stones is 0,
            else if (totalStone == 0){
                // Display an end game message
                txtaOut.setText(txtaOut.getText() + "\nThe game has ended.");
            }

}
public void playerMove(){
    // If there are no more stones left,
    if (playerInput() == totalStone){
        // Subtracting how much the player took from the total amount of rocks
        totalStone -= playerInput();
        // Displaying how many rocks were taken and how many are left
        txtaOut.setText(txtaOut.getText() +"\nYou picked up " +playerInput() +" stone(s). There are " +totalStone +" stones left.");
