How can i create 3 dependent drop down list with the 3rd drop down depending on 1st and 2nd list?

[CelineFoong]

Here is my list of data. For Dropdown3, I will want the dropdown to be dependent on BOTH Dropdown1 and Dropdown2. Kindly note that some of the values within Order Information/Shipping Information under Proforma Invoice/Draft Shipping docs/Final Shipping docs can be the same and it can be different too . As such I will need the 3rd dropdown list to be dependent on BOTH Dropdown 1 and Dropdown2

Dropdown1	Dropdown2	Dropdown3
Proforma Invoice	Order information	Customer requirement/basic information
Proforma Invoice	Order information	Payment terms
Proforma Invoice	Order information	PO number / Material information
Proforma Invoice	Order information	Price
Proforma Invoice	Order information	Quantity
Proforma Invoice	Order information	Vendor information
Proforma Invoice	Shipping information	Date discrepancy
Draft shipping docs	Order information	Customer requirement/basic information
Draft shipping docs	Order information	Payment terms
Draft shipping docs	Order information	PO number / Material information
Draft shipping docs	Order information	Price
Draft shipping docs	Order information	Quantity
Draft shipping docs	Order information	Vendor information
Draft shipping docs	Shipping information	Carton information
Draft shipping docs	Shipping information	Container information
Draft shipping docs	Shipping information	Date discrepancy
Final shipping docs	Order information	Customer requirement/basic information
Final shipping docs	Order information	Payment terms
Final shipping docs	Order information	PO number / Material information
Final shipping docs	Order information	Price
Final shipping docs	Order information	Quantity
Final shipping docs	Order information	Vendor information
Final shipping docs	Shipping information	Carton information

See the attached sample workbook.

Select C2 on the Data Entry sheet and click Data Validation on the Data tab of the ribbon to see the formula I used. It is

=OFFSET(Lists!$C$1,MATCH(1,(Lists!$A$2:$A$27=A2)*(Lists!$B$2:$B$27=B2),0),0,COUNTIFS(Lists!$A$2:$A$27,A2,Lists!$B$2:$B$27,B2),1)

It looks like it is exactly I have been looking for, but for some reason your Dropdown3 is not working.

Could you please let me know how to fix it?

Thanks a lot!

It looks like data validation has to be refreshed when the workbook is opened.

The attached new version is now a macro-enabled workbook; you may have to allow macros when you open it. I hope this works for you.

Thanks for your help and reply.

I am looking not to use VBA.

Please have a look on the file and see if you can help me.

Unfortunately, we cannot use functions such as SORT or UNIQUE directly in data validation. I don't see a solution without using VBA.

No problem!
Thanks again!

How do I make Drop down 2 dependant on the selection of Drop down 1 and Drop down 3 dependant on the selections of both?

Thank you in advance

If to google "excel dependent drop down list" lot of posts just on first page, e.g. How to make dependent dropdown lists in Excel | Exceljet. You may find more suitable in your case and your Excel version.

@Sergei Baklan thanks! I couldn't get it working using any of the guides online! I think the problem was that my data has multiple words and spaces and is very complicated against basic one word just a few items in a lot of the examples. I found a way to reduce the data down and cross reference using the Define Names - labelling each section of data as the simple name so it matches. 

It is a very over complicated way to do it and I am sure any updates to the data will break it - but it works for now. Thanks

In latest Excel it was improved, it ignores duplicates and blanks automatically. But all this is better to discuss on concrete sample if you have more questions.
