A table field referenced in a script can't be
found. Field_name is the name of the field that can't be located in
the table table_name.
Solution
Common solutions are:
Be sure the name of the field is spelled
correctly in the script. Also, be sure the field name was spelled
correctly when the field was created.
Be sure the field has been placed in the
table. You can verify this by looking at the list of table fields
in the Table Definition window for the table you're
referencing.
Use the Names feature to be sure you're
referencing the correct table.
