Randomly select a number multiple cells within a range based a cell value

Question

I would like to select a number of cells within a range (C7:M37), but some of the cells in that range are empty and should not be picked. In addition, the number is base on an equation (R41) so the number of select cells would be different each time. Is that possible? Thanks!

Answer 1

If you just use all cells it'll be :

=INDEX(C7:M37,RANDBETWEEN(1,ROWS(C7:M37)),RANDBETWEEN(1,COLUMNS(C7:M37)))

but if you want to ignore the empty cell .. need more info to be firm.. else it'll be a just a simple nested if="" .
