Hi Keith,
I presume you're in the embeditor, and these are the IDE Code-Completion suggestions you're talking about?
The first screen is showing you a bunch of local variables (create by the template) in that procedure. As you can see they're named based on your field names (on the form) and keep track of whether the field currently contains an invalid value or not. As you continue typing the code-completion narrows down the options for you.
cheers
Bruce
