Good day everyone, My plan is I'll checked multiple checkbox which is the pizza choices and a one radiobutton the pizza size and the checkbox values/prices are displayed in a textfield. I need to compute it and display it on the TOTAL COST textfield, I'll show you my work right now, it works but it only computes one checkbox.

Java

/*public double GreekPizzaPrice= 9.3, CaliforniaClubPrice=10.6,SpicyMexicanPrice=11.5,
	UltimateCheesePrice=14.0,BrooklynSpecialPrice=14.7,HSPizzaPrice=15.1,TexasFinestPrice=13.5,
	small=1.0,medium=2.0,large=3.0,total;
*/

	if(e.getSource()==compute){
		if(GreekPizza.isSelected()&&s.isSelected()){		 	total=GreekPizzaPrice+small*Double.parseDouble(MnuINum.getText());
		 	MnuTotal.setText(String.valueOf("$"+total));
		}
		else if(m.isSelected()){
			total=GreekPizzaPrice+medium*Double.parseDouble(MnuINum.getText());
	 		MnuTotal.setText(String.valueOf("$"+total));
		}
		else {

What is the problem. Note, the code you show is impossibly bad. Programming should not be done by repeating similar fragments of code. Do you know functions, function parameters, and other abstraction devices?

You are setting a text somewhere. Why?

You want to go through all of these cases - so there must only be if and all if must be on same level.
Also you want to create a sum of all cases that have been true - so do that:
