So zeigen die Felder nach einem Wert in einer anderen

Ich habe noch ein Kopf-scratcher eines Problems, das ich kann nicht scheinen, um eine Lösung zu finden für die.

Mache ich eine VF-Seite in der Hexe möchte ich Felder anzeigen nach einer Reihe eingefügt durch Benutzer in einer anderen Felder. Zum Beispiel, wenn der Benutzer legen Sie 2 in das Feld "A" wird die Anzeige in zwei Felder auf der gleichen Seite.
