Thanks, but the problem is that the field is NOT empty. It looks empty when I'm editing the content, but a value of January 1, 1970 actually gets stored (I know because when I return the value of that field with [types] it always comes out that way). So I need to know what that data looks like in the database so I can write an expression that checks against it- and if $start='January 1, 1970' that means that the field was intentionally left blank, and then I can complete my logic.
