Using a dropdown as a conditional?

Hello.

My QuickBase features a dropdown list that when selected, should automatically fill another field with today's current date.

Is there a way to check if anything has been selected in a dropdown? My best guess is something like this:

If([Dropdown] = TRUE, ...)

However, this throws me an error because the "=" operator cannot be used with textlists.

Any ideas as to how I can work around this?

I appreciate the help!
