MS Office Forum / Excel / Worksheet Functions / June 2007Conditional Formatting bug?
I’d appreciate help understanding why an apparently simple conditional formatting is not working as expected. A group of rows was formatted at one time but responded erratically to changes in cell entries. What I did was - *open a new workbook, *select rows 1-10 *in the Conditional Format menu, choose “Formula is” *enter =if($A$1=””,TRUE, FALSE) *choose fill color, for ex. red *hit the ENTER key *rows 1-10 turned red, as expected. Here’s the problem. When I typed into cell A1 a few random letters, some of the rows returned to the default color of white. Why not all? Even more confusing, if I minimize and expand the window, the formatting of all rows is now correct. The conition should be just: Formula Is =$A$1="" ________________________________________________________________________ > I'd appreciate help understanding why an apparently simple conditional > formatting is not working as expected.

With A1 empty............color With anything in A1.............no color rows 1:10 I think you should not be looking at Excel as the source of your problem. Perhaps a video driver issue? Gord Dibben MS Excel MVP >Thank you for trying. > [quoted text clipped - 23 lines] >> > is >> > now correct. Thank you for the reply. I also found an article on the Microsoft website (http://support.microsoft.com/kb/213243/en-us) titled "Odd refresh behavior after you specify a conditional format in Excel." Could this be applicable? Any advice on how to check the video driver?

Only you know for sure. Are you referring to a UDF? Doesn't appear so. Try with the shortened version of the formula and see what you get. Could be Excel is confused by the IF and TRUE, FALSE although as I said.........worked for me on 2003 I'm not a hardware person so all I can think of is to go to your driver manufacturer's site and download the latest driver.

Thanks for the advice. I entered the shortened formula. What happened was odd. If the cells were blank when I did the conditional format, I had the same problem. If I first typed something into the cells and then applied the conditional format, it worked the way it should - all cells either with or without color. I will try the manufacturer's site also. > Could the article be applicable? > [quoted text clipped - 61 lines] > >> >> > is > >> >> > now correct. Sounds like the cells have a space(s) in them.

Are you typing the $ signs for =$A$1="" to lock A1 as the trigger cell? Or did you mean =$A1 to lock just the column? Gord >Thanks for the advice. I entered the shortened formula.

I was trying to lock A1 as the trigger cell ($A$1). However I just tried it the other way ($A1) as you suggested, and the outcome was correct, i.e. color in row 2 or 3 or 6 when the cells A2, A3, or A6 were blank and white when I typed letters or numbers into the cells. Have no idea what's going on. > Are you typing the $ signs for =$A$1="" to lock A1 as the trigger cell? > [quoted text clipped - 75 lines] > >> >> >> > is > >> >> >> > now correct. > I was trying to lock A1 as the trigger cell ($A$1).

Have no idea what's going on - but will try this on my work computer tomorrow. If I don't have the problem there, it may be a driver problem as you suggested earlier. > > Are you typing the $ signs for =$A$1="" to lock A1 as the trigger cell? > > [quoted text clipped - 75 lines] > > >> >> >> > is > > >> >> >> > now correct. Tried this on my work computer and had the same issue so unlikely to be a hardware issue. Thanks to everyone who offered their advice. > > I was trying to lock A1 as the trigger cell ($A$1).
