    random name extraction without repetition

    Hello everyone, I have a problem with managing the customer database for a competition that we have announced.

    For questions of privacy I reproduced the problem inspired by football.

    I would like to know if it is possible to create a formula that allows me to use the Enter key (WITHOUT MACRO) to randomly extract from a list of names without the Player2 repeating the name extracted for Player1.
    I enclose the file (for greater clarity) containing:
    1.Ruolo
    2. Characters
    3.Equipaggiamenti
    4.Partita (sheets in which an object (two for equipment) must be attributed to each player without repetitions). It is not repeated what was extracted from Player1 for Player2 but he could extract the same equipment three times. Can you suggest me how to correct.

    If anyone can help me I would be extremely grateful.

    Buongiorno a tutti, ho un problema con la gestione del database clienti per un concorso che abbiamo indetto.

    Per questioni di privacy ho riprodotto il problema ispirandomi al calcio.

    vorrei sapere se Ŕ possibile creare una formula che mi permetta attraverso il tasto invio (SENZA MACRO) di estrarre casualmente da una lista di nomi senza che per il Giocatore2 possa ripetersi il nome estratto per il Giocatore1.
    Allego il file (per maggiore chiarezza) contenente:
    1.Ruolo
    2. Personaggi
    3.Equipaggiamenti
    4.Partita (fogli in cui un oggetto (due per gli equipaggiamenti) deve essere attribuito ad ogni giocatore senza ripetizioni). Non si ripete quanto estratto dal Giocatore1 per il Giocatore2 tuttavia egli potrebbe estrarre tre volte lo stesso equipaggiamento. Riuscite a suggerirmi come correggere.

    Se qualcuno riuscirÓ ad aiutarmi gliene sarei estremamente grata.

    Re: random name extraction without repetition

    May be this.
    In E5 then dragged across

    =INDEX(Equipaggiamenti!$A$1:$A$16,MATCH(LARGE(Equipaggiamenti!$B$1:$B$16,COLUMN(A$1)+((ROWS($B$5:$B5)-1))*COLUMNS($B$5:$E$5)),Equipaggiamenti!$B$1:$B$16,0))

    Pl note
    Array formula should be confirmed with Ctrl+Shift+Enter keys together.
    If answere is satisfactory press * to add reputation.

    It really seems to work. Very interesting also the use of the + operator! I didn't know it.
    Thank you very much.!!!
