     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act() 
    {
        // Add your action code here.
        if(Greenfoot.mouseClicked(this)){
            Counter counter = ((BeliHewan)getWorld()).getCounter();
            if (counter.getValue() > 100)
            {
                Greenfoot.playSound("ChaChing.mp3");
                counter.walkCount(counter.getValue()-100);

We can't use nested if in the act method?

Well if you are able to play the sound it must mean that the if statements work fine. Can you show the code for counter.walkCount? Preferably the whole counter code.

What is the initial value of the counter when the button is clicked?

well, I've change the code like this.. 
Animals an = new Animals();
        Counter counter = ((BuyAnimals)getWorld()).getCounter();
        if(jRadioButton1.isSelected() && counter > 700){
            counter.walkCount(-700);
but it show an error : bad operand types for binary operator '>' first type : counter, second type : int do you know where's the problem?? when I tried to change the code like this 
Animals an = new Animals();
        Counter counter = ((BuyAnimals)getWorld()).getCounter();
        if(jRadioButton1.isSelected()){
            counter.walkCount(-700);
It works, but when I buy the Animals without the (counter > 700), the gold will be reduce till negative if we don't have a 700 golds :((

    public void walkCount (int amount) 
    {
        // Add your action code here.
        count += amount;
        setImage(new GreenfootImage("Gold : " + (100+count),20, Color.WHITE, Color.BLACK)); 
    }    
    
    public int getValue(){
        return count;
    }

The error message is saying that you cannot treat a Counter object as a value. You need to get the value of the Counter object and compare that to 700.

No need. Just use counter.getValue().
