When {{cs1}} and {{cs2}} templates contain {{para|jfm}}, a test is done to see if the [[Jahrbuch über die Fortschritte der Mathematik|JFM]] identifier value looks like a properly defined value. The {{para|jfm}} identifier is checked to make sure that it has the form: <code>nn.nnnn.nn</code> where <code>n</code> is any digit 0–9. Further validation of the JFM identifier is not performed.

To resolve this error, ensure that the {{para|jfm}} value is correct.
