Dear Sirs,

I wish to do a picklist of all the values I have in a field where the date has not been filled yet.

However I'm not able to search for null or "" or Empty dates.

The Script I'm using without success is:

AWB
    (
        type  =  list
        values  =  Control_Valijas[(Fecha_Arribo is null)].AWB
    )

Do you have any solutions to this issue?

Thanks for your help...
