Hello fober1,
You had responded to one of my posts and provided this sample code below, which I modified slightly and use, and it works great :

return(error);

function show(){

My question is how can I add a line item number to each row. The first row will always appear and have line item 1. If the add/next button is selected to add another row, then that line it would be 2, etec., all the way up to 10. I had some ideas and tried it but then the code stopped working, so I just put everything back.
