Not necessary, you can see all the javascript.

@OP: the alert that says:

You have entered either a discontinued / invalid item number
or an old 6-digit Fypon item number.\nPlease contact customer service at 800-237-7470 for assistance.
Thank you.

The alert message pops up even though it works. meaning that it finds the part number and adds the price to the right column but the alert message still pops up. The problem i am having is in the first row only. That is where it has the auto complete drop down.

to test it go the first row and push any letter when the part number comes up click that and it will put it in the field. then the the cost will add into the third column. that part is right but the error message still pops up.

But if you put that same part number in the second row then it works 100%.

Thanks for the help and sorry that the first explanation was so short. This thing has been pissing me off for the last two days.
