Create a script to log changes to a drop-down list?

[BowDown]

Only way I can see of doing this is making the field a button, have it launch a script, then prompt the user for the value they want to change the field to. Then add an entry to another table that will track the change. But when I prompt the user I can't do it in a drop-down list format?

Is there anyway to make it auto complete or show a list on the custom dialog box?

Take a look at several example files I have on my web site:

These techniques are very different in their results and their implementation so consider the advantages and disadvantages wisely.
