If, upon first opening the Microsoft Word Application there is a bar at the top saying Macros need enabling, make sure you enable Macros so that programs can work. If variations occur in your following of these steps, ultimately the goal is to press that play button. If a box comes up unrelated to the program, close that box and re-select your form.
Hopefully this helps you if you didn't know how things worked before, and that it lets you mess with some interesting amateur level applications.
To view code, the button besides View Object labeled View Code will show the code for that Form.
