RESOLVED
I just needed a few hours break.
I do, however, have the remaining issue that I know how to ensure that an form option menu displays whatever is the current value through a piece of coding such as:
<option value="A" <?php if(($rsQuery->getColumnVal("Whatever")) == "A") echo ("selected");?>>Value A</option>
However, when "Update" has been pushed, the option menu does not immediately update itself. It is instead necessary to manually re-upload the page.
I find this clunky, and would prefer something more dynamic. I have read on Google that a piece of Ajax or Javascript code will do this, but have yet to find an example. If you know how to do this, I would be obliged, thank you
