An empty selection in a drop down list

    In Manage Database Files I have created a TAB with a number of Groups within the TAB. For the FORM ELEMENTS I have used Drop-Down List. My Drop-Down List has the following options [Anthropology,History,Travel etc etc]. In the record entry form all the fields are initially empty. If I then set a field to say History and save it, then later on I want to reset it back to empty, how can I do this? If I use ” ” or ‘ ‘ etc, those values simply come up in the Drop-Down List. Is there a special code or character I can use at the head of the Drop-Dowm List to represent an empty field.

    Many Thanks again…

    You can use a “null_select” item to blank out the value, like this

    null_select::,Anthropology::anthropology,History::history,Travel::travel

    Take a look at the documentation on setting “values” for select fields for an explanation of using “null_select”

    Absolutely fantastic does exactly what I want and more. It’s just a question of being able to find what you want in the documentation.
    Many Thanks
