Could you give me a function for "If G11 and H11 are blank then make a range nofill (NoColor).

I've never done functions so I am pretty green.

Yo :roll:

I thinks this is what your after

Highlight the range you want, go to Format -> Conditional Formating
in the first box change "Cell value is" to "Formula is" then put this formula in the box
=IF(AND(($G$11=$H$11),($G$11 = "")),1,0)
then on format button choose No Fill

Just a quick follow-up to Dave's advice, if you want the conditional formatting for an area larger than the two cells, you will have to adjust the relative cell refernces (i.e. $G11 or G$11) to make sure that the entire selected area is appropriately formatted.
