Hi EE-r's - It's late and I just cannot get this.
Simply need a formula that will give answer in all cases as follows:
Have 3 columns
col 1 is an amount positive, neg or zero
col 2 is the same
col 3 needs to be the difference between the two stated with the correct sign
I can get it to work mostly but when pos and neg numbers flip flop it gets cranky.
