Ok...Here goes. Finally got this really nice IF statement to work:
=IF(A2(6/7), 1, IF(A2(5/7), 2, IF(A2(4/7), 3, IF(A2(3/7), 4,
IF(A2(2/7), -1, IF(A2(1/7), -2, 0))))))

This is in cell B2

Assigns a value to a random number in A2, and gives seven different outputs
of +1, +2, +3, +4, -1, -2, -ALL

What I want to be able to do is have one cell keep like a running total.
That is, start a cell at zero (we'll say C2), then if the random number is
between 6/7 and 1, add 1 to the C2. Then when i hit F9 again and a new value
comes up, for example, the random number is between 4/7 and 5/7, add 3 to C2
so that now it says 4. Is this possible? I tried:
=IF(A2(6/7), C2=(C2+1), IF(A2(5/7), C2=(C2+2), IF(A2(4/7), C2=(C2+3),
IF(A2(3/7), C2=(C2+4), IF(A2(2/7), C2=(C2-1), IF(A2(1/7), C2=(C2-2),
0))))))

And other variations. Also tried in C2 :
=$C$2+B2 and
=C2+B2
but those just start a circular reference. Thanks for any help.
