}

can someone give some advice or hints on how i can display:

the items, prices, cash and change for this...

example:
--------------------------
Receipt:
Items:

[1.] T-Shirt = 500
[2.] Jeans = 1000

total=1500.00
--------------------------
cash = 2000
change=500


and also how to make the amount display even if its more than 1,000.00 coz when I choose an item more than 1,000.00 it displays 0.00....

plz help
