    You probably need to change a couple of your current formulas. As it stands F12 can only be "Academy" when the rand() value chosen in K12 is exactly zero, which is very unlikely.

    Presumably you want an equal chance of each K1:R1 value selected so change K12 to

    =RAND()*8

    change L12 to

    =INT(K12)+1

    [these could be combined in 1 cell as =INT(RAND()*8)+1]

    then in F12

    =INDEX($K$1:$R$1,L12)

    and in G12 to select, randomly, entry 2 or 3 from the same column

    =INDEX($K$2:$R$3,INT(RAND()*2+1),MATCH(F12,$K$1:$R$1,0))

    No problem....

    Thinking about it, I suppose there's no need for MATCH function, you can replace MATCH(F12,$K$1:$R$1,0) in G12 with just L12
