I wrote a formula for a cell in a column, then copy paste the same formula in whole column means all cells under the upper cell, by mistake in the middle of column , I changed the formula. I forgot my mistake, the value of that mistaken cell had changed , and calculations result went wrong, I want such conditional formatting that that particular mistaken cell should automatic change it's color, and alarm me that in the whole column that cell has different formula from the other cells of column ??
