I hope I can say this - I browsed around, found a script that I was pleased with but it wasn't really what I wanted and it took some time to implement for what I wanted to do. I have multiple forms and multiple uploads of different types.

I browsed and tinkered more and then just got CoffeeCup form builder. (Can I say this - the company that is? I guess we'll see!) I'm pleased with it and have had no security issues at all.
