Hi how do you test if a property is empty, Im trying to copy a value from one object to another but its fail if the property has not been set in the original object , Ive tried variuos checks such as is empty, !=, is missing and none of them have worked
(or compiled in most cases)

Are we dealing with a property RECORD here?
Sorry I dont know Im a novice, Im looking at properties of a track object within iTunes

the played date field is of type date, just checking with
if (played date of orig_track is not "")
doesnt work because its never equal to this whether it has a value or not, whereas it does work for EQ
which is defined as Unicode text
if (EQ of orig_track is not "")
