So, poste hier jetzt mal die neueste Version. Bei weiteren Änderungen ändere ich dann die und mach keine neue, so sollte das gehen.

Einer der dümmsten Fehler war mal wieder, das ich aus ner ´normalen´ eine tk-Variable gemacht hab, und im Vergleich das ´.get()´ vergessen hab...Naja, jetzt sollte es einigermaßen laufen. Jetzt wird auch die Eingabe automatisch in floats umgewandelt.
