Having trouble making a function that returns multiple values for index match.

Currently trying to create an index function that returns multiple values horizontally. Currently when I run this formula using ctrl + shift + enter I get an #N/A

Current formula: =INDEX($B$2:$B$150, SMALL(IF(A$2=$C$2:$C$150, ROW($C$2:$C$150)-MIN(ROW($C$2:$C$150))+1, ""), COLUMN(A1)))


Ideally cell D2 would be cgsteen

Welcome to the forum.

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

1. I think you meant vertically (up-and-down), rather than horizontally (side-to-side)?
2. Delete/fix the errors in the lower part of your table.
3. why would cell D2 = cgsteen? A2 = EB-101 and it's 1st match is in row 94 - helle029

Also, if your references in col A are unique (which your sample indicates), why are you using a complex ARRAY functoin for that, when a simple INDEX/MATCH will do the job?
D2=IFERROR(INDEX(B:B,MATCH(A2,C:C,0)),"")
