[Javascript] counting selects

[Julien Nadeau]

Richard Garbutt got the problem right. That's why I was suggesting to  
do it like this:

replace:
     if (inputFields[i].getAttribute("name") == "products_id[] 
[products_quantity]") {

with:
     if (inputFields[i].getAttribute("name").substring(0,11) ==  
"products_id") {

But as Richard said, you can also replace
> if (inputFields[i].getAttribute("name") == "products_id[" + i + "] 
> [products_id]") {

by
> if (inputFields[i].getAttribute("name") == "products_id[" +  
> orderNumRows + "][products_id]") {

and it should work.
