I have a couple forms that generate a unique ID based on taking the highest number in the ID column adding 1 to its value. The problem is that I don’t save that number until the form is submitted. If 2 or more persons fill out the form at the same time they all get the same ID number. I hope that there are some suggestions on how to accomplish this with a better methodWhat database are you using? Pretty much all of them have a method for generating these numbers internally.
