Hi,
I gave you one solution earlier, now here is another - which Microsoft says
can't be done.
1. In the Engineers workbooks name the range containing the serial numbers,
here I named it Data. (highlight the range and choose Insert, Name, Define,
type Data into the Names in workbook box and click OK).
2. Move to your workbook in an empty cell type = and then click on any cell
in the other workbook to build a formula like
'[10-21-2008.xls]Sheet2'!$A5
3. Edit this formula so it reads
'[10-21-2008.xls]Sheet2'!Data
Press Enter and the formula will change to
='10-21-2008.xls'!Data
4. Highlight the formula on the Formula Bar and copy it, press Enter once to
escape the Formula Bar
5. Choose the command Insert, Name, Define and enter a name like FSE1 in the
Names in workbook box (if you are using 2007 make it four letter followed by
a number to be on the safe side)
6. Click in the Refers to box, clear the existing entry and choose Paste.
This should paste the formula from step 3 into the Refers to box. Click OK.
7. Select the range with your serial numbers say A1:A100 and choose Format,
Conditional Formatting, Formula is from the first drop down, and in the
second box enter =OR(A1=FSE1) pick Format and choose what you want. Click
OK twice.
Remember Microsoft says you can't use external references in Conditional
Formatting, but apparently you can!
If this helps, please click the Yes button
Cheers,
