Tabellensortierung - wo ist der Fehler....?

Ingo Homepage des Autors 03.04.2024 15:06
Hallo ihr Lieben!
Ich verzweifle gerade an einer simplen Tabellensortierung...
Wenn man auf HERSTELLER klickt, klappt alles wunderbar - man kann die Tabelle auf / Absteigens sortieren.... Wenn man aber TITEL anklickt, sortiert es einmal die Daten aufsteigend - danach passiert nichts mehr - klickt man davor wieder auf HERSTELLER, funktioniert die aufsteigende Sortierung erneut, absteigend ist jedoch scheinbar unmöglich umzusetzen...
Hier der Code meines Files - ich bin für jede Hilfe wirklich sehr dankbar...
