Hello, friends. I Have table like
quantity size price total
1-10 large 15 changed as the quantity increase
1-10 Middle 15 ....
1-10 Smalss 15 .....

total price sum of this column


I could be able use
function QuantityChangedL(qty) {
document.getElementById ('totalL').innerHTML = qty * document.getElementById ('price').innerHTML
}......

to get the each row's total value there, but how should I make the code so that the last row's total price can change according too!

Thanks very much in advance!!
