Form Values On Asp Edit Page???

I'm trying to setup something that adds/edits records to an access db using vbscript.

I've got an html form with text, select and textarea inputs.

These values get passed to an asp page that UPDATES the record (not INSERT because it's actually appending to an existing record). Because this page is also an EDIT page, I SELECT all the values so as to:

1) display the current value for editing

2) make sure if they're not edited the value is not null when submitted

My questions:

It's no problem populating the values of form "text" inputs, but how do I do the same for

a) the "select" inputs (Make the proper value SELECTED)? and
b) the textarea input?

ie. The user goes to the page for the first time and there aren't any values yet. They use the various form inputs to add values. When they come back to edit the same record I need to display current values of all form fields properly. Code:
