use INDEX formula in Excel for gathering multiple search items

[Half Measures]

On the "List" worksheet, I have an inventory of Food, Music, Activity and Color that a Customer uses listed into columns. On a "Search" worksheet I have created PickLists cataloguing the Food, Music, Activity and Color available for Customers.

My goal with this is to create an INDEX formula for finding which Customers are utilizing a chosen item from the PickLists? These would be done by aligning the Row of a Customer and Item listed that they are using, from the "List" worksheet. A VLOOKUP formula only shows one result, and only shows the first one in the search. I’m looking for a way to result all the Customers using the chosen item.

I wanted to attach the Excel doc here that I'm talking about, for a better example. But, I couldn't find a way to do that. I'm new here. So, here are some screen-shot's visualizing what I'm talking about.

The formula does not exclude duplicate values, because you never said it should.
If you are missing values then it's probably because on the list sheet the values are not exactly the same as D2. Check for typos & leading/trailing spaces.

how do I "exclude duplicates"?

I'm not seeing any "typo's" either.

Try

=IFERROR(INDEX(List!$D$2:$D$8,AGGREGATE(15,6,(ROW(List!$D$2:$D$8)-ROW(List!$D$2)+1)/(List!$A$2:$A$8=B$3)/(ISNA(MATCH(List!D$2:D$8,B$6:B6,0))),1)),"")

This might get rid of both problems, as the original formula was missing a $ sign.

Cool. I'll leave you alone for now. Gonna edit it and call it a day. Got some other things I need to do before I close it down. Thanks again. This is a great forum to use.

I think I have it working now, using that new formula you posted yesterday. No duplicates, and all Customers are showing now. Thank you, again. I really appreciate your help with this.

Glad it's working & thanks for the feedback.

Everything was working fine. But, after saving it and opening it back up, the results stay frozen and do not work anymore?

Is calculation set to manual?

How do you check that? Not sure what you mean, or how to fix it to what it should be.

On the formula tab click "Calculation options" & make sure it's set to automatic.
