I may be overthinking this. I have 5 fields that take numbers. I dynamically add the contents of the fields together and display the result in another field using some simple jQuery. If there is form validation on for another field (say, a radio button, for example) and I forget to fill that field out, I go to the standard EE error page...which is fine. When I go BACK, what I would like to see are the fields being repopulated - including the one that was totalling the other fields.

Is there some sort of post array I can loop through to get those values back and re-populate the fields?

You just ran up against one of those annoying browser things. Some browsers remember the form, others don’t. Cookies may be your only option.

Yeah. Nasty problem.

I think if the user has JS on anyway, and I add jQuery validation, I’ll catch all the errors before the page reloads, which will help. Onward with jQuery validation!
