    Shawn,

    How do search for null?

    I want to find all payments that don't have anything in the notes field.

    Any ideas?

    Regards,

    Your loyal fan

    that is not correct... this is an empty string... not a null...

    try this:
    in SQL, use the words "NULL"
    in visual basic, use the "isNull" function
    in C, check for "\0"

    The equal sign (by itself) is what you are looking for.
