Excell Conditional Formula

One way would be to create a colunn C and use the formula: =COUNTIF(B$2:B$200,A2) in cell C2. Then copy the formula down to C200. (assuming you have 200 entries in B...). This will put a "1" next to every number in Column A that has a match in column B. Then you could put a conditional formula in column A that will highlight the cell if the value in column C is equal to 1. Alternatively you could also simply filter for 1's in column C and then manually highlight the cells that show up in A!

option: formula is
formula: =(datecell="")
select formatting of choice

Highlight the order cells, go to >format>conditional formatting, choose "formula is" instead of "cell is". When you refer to the datecell, use the first date cell in the column only, and do not use $ signs.

Format cells A1 and B1 to dates.

A1 is the first date
B1 is the 2nd date
C1 enter the formula below

=DATEDIF(A1,B1,"y")&" years "&DATEDIF(A1,B1,"ym")&" months "&DATEDIF(A1,B1,"md")&" days"

Need to have a greater than or equal to on one otherwise excell will get confused.

Enter data the number 10 on cell A1. Enter data the number 20 on cell B2. Mouse click on cell C3. Press equal sign, press left arrow, press *, press left arrow twice, press enter. Mouse click on cell C3. You'll see your formula on the address bar. Hope this helps.

CUSTOM FORMATS
Custom Formats
Excel see a cells format as having four Sections. These are, from left to right: Positives;Negatives;Zeros;Text.

To hide zeros cell-by-cell use a Custom Number Format like 0.00;-0.00; where 0.00 is desired format for non zeros. Note the use of -0.00 for negatives.

To hide zeros on the Workbook level go to Tools>Options>View - Zero Values.

You should use the formula COUNT (Cell1, Cell2), please replace Cell1 and Cell2 for the range of your cells in Excell. You could use too the formula COUNT.IF(Cell1,Cell2,Criterion), Cell1 and Cell2 is the range of cells when can exist an entry.
Example The final formula is like:
COUNT(A1:A5)/COUNT.IF(A1:A5,"=x")*100
