Would you accept a suggestion from someone other then Tina?
Let's say that the completion date column is G, and the target date column
is D.
Data of concern is in G2 to G50 and D2 to D50.
Select G2 to G50, with the focus in G2 (colored white), then:
<Format> <ConditionalFormat>
Change "Cell Value Is" to "Formula Is",
And enter this formula in the window:
=AND(G2<>"",G2=D2)
Then click on <Format>, and choose a yellow format (font or pattern),
Then <OK>.
Then click on <Add> for your second condition.
Again change "Cell Value Is" to "Formula Is",
And enter this formula in the window:
=AND(ISNUMBER(G2),G2<>"",G2>D2)
Then click on <Format>, and choose a red format (font or pattern),
Then <OK>.
Then click on <Add> again for your third condition.
Again change "Cell Value Is" to "Formula Is",
And enter this formula in the window:
=AND(G2<>"",G2<D2)
Then click on <Format>, and choose a green format (font or pattern),
Then <OK> <OK>.
So, you now have set your 3 conditions to color the cells when Column G is
not empty, and when Column G does not contain text.
