I have tried the following as the Conditional Formatting Custom Formula: Where B2 is the current cell:
COUNT(FIND("$B$1",FormulaText(B2)))>=1
the formula in B2 is A2*$B$1 in B3 is A3*$B$1 etc. - but some cells do not reference B1
If I paste this into a cell/range in column C:
=COUNT(FIND("$B$1",FormulaText(B2)))>=1
then it correctly returns true or false depending on the formula in the adjoining cell.
However when applied as a conditional format it is not changing the format of cell B2
I also want this formula to apply to a range of cells - but it seems to apply the identical formula COUNT(FIND("$B$1",FormulaText(B2)))>=1 to each cell and not change B2 to B3, B4, B5 etc.
