Formula/Array to return results in a certain range

**B_Riz** · 01-30-2011, 12:06 AM

Hello all. I'm new here and have been trying to figure out the best way to write this formula.
It's been giving me a headache trying to figure this out.
The rundown:
I have a simple sheet which shows 3 columns: "Date", "Contract#", & # of Contracts"
(Please click link to see simple spreadsheet showing example)

The contracts all contain 5 or 6 #'s which contain numbers from 1-30. Each # in the contract represents different stages in the billing process.

I need a formula/array that shows which #'s are not appearing within the range 1-30 for the entire group of B2:B9 (not individually, but for the entire range).

So, please see below list in BOLD RED in the range B2:B9... I've highlighted numbers below are not appearing:
1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22-23-24-25-26-27-28-29-30

I need a formula which will shows the #s in BOLD RED since they are not appearing in the range 1-30 in the cells B2:B9

I hope I didn't make the questions confusing.

Thank you in advance, I really appreciate the help!

roy - I wasn't certain how to title this as I was not sure exactly if it would be considered an Array or a standard formula. I thought I was being direct in the title by explaining "Need help with formula" as that is exactly what I need...Help with a formula.

Thanks for the heads up, I have changed the title and hopefully it meets your standards.

You can do it with a formula but you'd have to list each missing number in a separate cell, and the formula will be quite complex. Perhaps easier to use conditional formatting, e.g. list numbers 1 to 30 in E2:E31 and then select that range and use this formula in conditional formatting

=COUNT(SEARCH("-"&E2&"-","-"&B$2:B$9&"-"))=0

Missing numbers are highlighted, see attached

Daddylonglegs - thank you very much for the help & info. I tried that formula you listed but for some reason it is getting an error & not working for me. Any ideas why this isn't working? I created separate column (E) containing the values 1-30 as you mentioned (E1:E30).

Thanks again!

Hi B_Riz,

Just wanted to check where you have applied your formula? I tried solution Dadylonglegs have given and got the results, told by him.

I think you have doubt in that.
What you need to do is, after filling values in E column, select the range, go to conditional formatting. Click on "Use a formula to determine which cells to format" under select a rule type,

Put the formula =COUNT(SEARCH("-"&E2&"-","-"&B$2:B$9&"-"))=0 under "Format vales where Formula is True," category, then click "Format" button on the lower RHS. Click OK to apply the formatting.

"Daddylonglegs" good efforts.
