I am using Google Form for my customers to submit their opinion. I read [this][1] and [this][2], but I have some questions which these two posts haven't mentioned. Is it possible for my customers to know their submission ID when they see the confirmation page? E.G.: > Thanks for your response. Your reference no. is #S201501. We will contact you within 7 days. The second customer will have #S201502… etc. Can I also check the reference no. in my original spreadsheet?
