Your initial solution was SO much better than mine. So that's the one I'm using.

I needed to find the first random non-blank element. Using shuffle worked, but I was looking for a neater and simpler way.

Again, thank you.

My final - 

        while (1) {
            my $xda = int rand $total + 1;
            if ( defined $aob[$xda][ $y - 1 ] ) {
                $aob[$x][$y] = $z + $aob[$xda][ $y - 1 ];
                last;
            }
        }

. Using 'defined' is actually better in this case than using "" or q{}. No warnings.
