So, let me get this straight.
You just need a user (techie) editable database entry and a way to view it?
My friend, you have already spent more time scrounging than it would take programming.
Here's some pseudocode (or as a guy I once knew used to call it, "Swayedocode"):
program one:
connect to database
extract current value from database
form with text field (set the value='$dbvalue') and submit button
posts to itself
if there is a value in the variable sent from the text field, change the DB value
program two:
connect to database
extract current value from database
display value
I'll do it for you for $50.00. $75.00 for adjustable formatting.
