I am currently trying to highlight cells that the formula cantains a cell
that was changed within another worksheet thru multiple formula calculations.

For example, in sheet A I have a list of data. This value is then used in
approx. 20 other cells and worksheets (all are within the same workbook) by a
direct formula and also by indirect formulas. I would like to highlight all
the cells that are affected by me changing the one value to another value.
