My question is simple, though I imagine the answer may end up being beyond my skill. I have a form, which has multiple check-boxes, buttons, etc. I want to add an 'Undo' button that will step back (even if it's only one step back, and can't go back multiple steps) whenever clicked.
I have been all around search engines trying to get even a starting point, and to my surprise, I have found very little that was any help at all to me.
If anyone can help me, it would be much appreciated, as this project's deadline is 10/10, which is in less than 2 days, lol. If all you have is code that I can use, that is fine, but I would very much like to understand how it works so I can work with it more in the future, so an explanation, or link to a tutorial would be wonderful.
