Thread: Cannot add values

for: double mediumSubTotal, I want to declare MEDIUM_RATE * medium + childSubTotal, but it's giving me a syntax error "cannot find symbol" when I try to add childSubTotal

private void childButtonMouseClicked(java.awt.event.MouseEvent evt) {                                         
 
        childCounter++;
        childQuantity.setText(String.valueOf(childCounter));
 
        int child = Integer.parseInt(childQuantity.getText());
        double childSubTotal = CHILD_RATE * child;
        double childTax = childSubTotal * MD_STATE_TAX;
        double childTotal = childSubTotal + childTax;
 
        subTotal.setText(String.valueOf(fmt.format(childSubTotal)));
        tax.setText(String.valueOf(fmt.format(childTax)));
        total.setText(String.valueOf(fmt.format(childTotal)));
 
    }                                        
 
    private void mediumButtonMouseClicked(java.awt.event.MouseEvent evt) {                                          
 
        mediumCounter++;
        mediumQuantity.setText(String.valueOf(mediumCounter));
 
        int medium = Integer.parseInt(mediumQuantity.getText());
        double mediumSubTotal = MEDIUM_RATE * medium;
        double mediumTax = mediumSubTotal * MD_STATE_TAX;
        double mediumTotal = mediumSubTotal + mediumTax;
 
        subTotal.setText(String.valueOf(fmt.format(mediumSubTotal)));
        tax.setText(String.valueOf(fmt.format(mediumTax)));
        total.setText(String.valueOf(fmt.format(mediumTotal)));
 
    }

Is it because the first method is private? How can I fix this?

I'm using NetBeans GUI builder
