Form Actions

I'm new to Zoho Creator... and I know a bit about scripting as I took a course or two in college... however, I'm pretty rusty. Is there some kind of guide to familiarize myself with the scripting? It says that I don't need to be a programmer, but I've looked through all the help and FAQ sites that Zoho offers and I still don't know where to begin. Is there some kind of introduction to scripting? I'm looking at the form actions for the "on submit" and don't know where to begin. Any help would be great!
