To function properly, some parameters are limited to a certain set of acceptable values.  This error message indicates that a parameter has been assigned a value that is not a member of the parameter's defined set of acceptable values.

To resolve this error for the parameters in the table, use an appropriate value.

Support for {{para|ref|harv}} is withdrawn because cs1|2 templates now automatically create the <code>CITEREF</code> anchor value that {{para|ref|harv}} controlled.  To resolve this error, remove {{para|ref|harv}}.
