This tutorial explains how to have Insert, Delete and Update actions on a single page. The reason I created this was because I did not want to create various forms for certain tasks.
Instead of using three forms or three pages here is a one page solution that works well for what I wanted to do.

The form posts to itself picking up the hidden value and performs the action. 
I also added a function to deal with single quotes.

This tutorial assumes you have limited knowledge of handcoding.
It utilises UD's connection string, it's also based on frames.

I will be updating this tutorial in the next couple of weeks.
