Some fields need data. This function shows your users IN THE FIELD which fields need data by displaying a red '-- enter data--' in the field.

Since this function uses the Auto-enter calculation function of FileMaker, it can also enter data automatically. Be sure to unmark the 'don't override data entered' checkbox.

ThisField: The value of the current field
CheckField + CheckValue: The text '-- enter data --' is only displayed if CheckField contains CheckValue (can be empty too).
StandardValue: Auto-enter a value when no data is entered. This is almost like the FM function Auto-enter data.
