I don't want the engineer to be able to digitally sign the form unless they have attached a particular check sheet file. I have a list box that displays the file names of all files the user attaches. I need JavaScript that will look for the attachment file name "Supplier Check Sheet" in the list box and if found, then allows the engineer to sign the form. If not found, i will have an error message appear. If you can tell me how to search for the file name in the list box, I can probably do the rest.
