the program works but you see i can't do that cause according to our prof the output should be.....

we can input any number in any field... what i mean is there is an option that i can only choose one,two,three or four books(to check/choose)..... so what you are saying will not work for the program....

can u give me a better solution/code for this.

my head is turning upside down.

are you available in the evening??? cause its 1 am here in the philippines .... and i'm kinda sleepy... hehehe.. if you dont mind

Exactly my point zedenaka, therefore you should check every textfield if it has value,
if there is a value then parse it if there isn't then set the integer variable that corresponds with the field to 1.

You misunderstood me here:

this way it only works when the four fields are filled

never mind this and try as I tell you

[zedenaka]

i've already got it!!! tkanks a lot... i've done it like this

if(hpBox.getState())
		{
		qty1=Integer.parseInt(qty1Txt.getText());
		tp1=qty1*up1;
		tp1Lbl.setText("P " +tp1);
		}
		else
		{
		qty1=0;
		tp1=qty1*up1;
		tp1Lbl.setText("P " +tp1);
		}

but i still have one problem... when i click the reset button all the fields should be erased/removed and the checkbox/group should also be empty cause i set it to false... but the checkbox group isnt empty.... do you know why??

	
	if(arg=="RESET")
		
	{
		hpBox.setState(false);
		lotrBox.setState(false);
		aiwBox.setState(false);
		pBox.setState(false);
		qty1Txt.setText(" ");
		qty2Txt.setText(" ");
		qty3Txt.setText(" ");
		qty4Txt.setText(" ");
		tp1Lbl.setText("P");
		tp2Lbl.setText("P");
		tp3Lbl.setText("P");
		tp4Lbl.setText("P");
		cash.setState(false);
		twop.setState(false);
		threep.setState(false);
		tqLbl.setText("Total Quantity:");
		priceLbl.setText("Price:");
		interestLbl.setText("Interest:");
		taLbl.setText("Total Amount:");
		
	}

[PennyBoki]

yes try instead of if(arg=="RESET")
to put this
if(arg.equals("RESET"))

[zedenaka]

hmmmmmmmm it still wont work.... the selection i've made with the checkbox group isn't removed...

[PennyBoki]

ok here we go again post the new code all of it.
