I have a list in 'sheet1' that contains names. B3:B23
In 'sheet2' I have 2 columns that I want to use to pair the list in random
order.
I used this formula in column A
=INDEX('Sign-Up Sheet'!B3:B23,RANK(OFFSET($K$1,2*ROW(A1)-1,0),K2:K24))
And this formula in column C
=INDEX('Sign-Up Sheet'!B3:B23,RANK(OFFSET($I$1,2*ROW(E1)+1,0),I2:I 24))
Column I & K use the =RAND() formula

The problem is that it has duplicate names instead of matching unique pairs.

Thanks for helping!
