Autovalg part II

Hvorfor virker dette så ikke?

Det programmet skulle var at når jeg indtaster et bogstav i et kl. 8-9 felt skal dette kopieres til 9-10, 10-11, 11-12, 12-13, 13-14, 14-15 og 15-16. Tilsvarende hvis jeg taster et bogstav i et kl. 16-17 felt skal dette kopieres til alle felter fra 16-20.
Hvorfor virker det ikke?

Kunne man få det til kun at ændre de felter der har at gøre med den man har ændret, således at jeg kan overskrive de øvrige valg.

Eks. Jeg indtaster A i feltet Man8-9 og dette kopieres ud.
Jeg indtaster X i feltet Man14-15. - Det skal blive stående (det gør det vidst ikke _hvis_ programmmet havde virket).
Jeg indtaster A i feltet Tirs8-9 og dette kopieres ud. - Men uden at slette mine indtastninger for mandag, incl. man14-15 feltet.
