I have the following function to get the total qty:

function calttl()

{

var ttlqty

ttlqty=0

for (i = 0; i <= document.qtymain.orderdetail.length-1; i++)

{

ttlqty = ttlqty + document.qtymain.qty.item(i).value

}

}

The problem I have is the document.qtymain.qty.item(i).value I get

look like a string, so the number I get for ttlqty is not add up the

number but concatenate.

How do I convert the value I get to a number in javascript?

Thanks for any help in advance.
