Sum of Questionnaire Scores Based on a Domain Table - excel

Question

I have created a questionnaire that consists of around 100 questions. Participants are asked to fill them in online, where the items are shuffled each time. These items are separated into 6 domains where, for the sake of easier understanding, let's just call them Domain 1 - 6.
I have them typed in one specific table called "Correspondence", with format like below:
(An example)
Question No.|Domain
　　　1　　|Domain A
　　　2　　|Domain C
　　　3　　|Domain A
　　　4　　|Domain B
　　　5　　|Domain A
　　　6　　|Domain C
I used Google Form to generate a spreadsheet of RAW data of respondents, where it will help me mark the RAW Scores, for each item on a separate column:
(An example)
Submission ID|Question 1|Question 2|Question 3|Question 4|Question
5|Question 6
Participant 1　|　　2　　|　　3　　|　　5　　 |　　1　　 |　　2　　 |　　4　　 |
Participant 2　|　　5　　|　　4　　|　　5　　 |　　3　　 |　　5　　 |　　1　　 |
Participant 3　|　　1　　|　　1　　|　　1　　 |　　2　　 |　　2　　 |　　2　　 |
The next thing I need to do is generate another table that sums up the Domain totals for each participant. So from the example above, I need to sum 1,3,5 as Domain A, 4 as Domain B and 2 & 6 as Domain C:
(An example)
Participant 1
　　　　|Domain A|Domain B|Domain C|
Total　|　　9　　|　　1　　|　 7 　　|
The hardest thing is to find a proper method to kick start this process. Can anyone point me in the right direction? Either formulas or VBAs would be fine too. Thanks!

Answer 1

This can be done if you are able to create a helper row.
First, I created a table to link the question to domain. That is named in my example as "Correspondence". This table is somewhat the answer key. From your description of the problem, you need a table like this to establish which question is associated with the domain/category/point system you want to use.
I then created a helper row for the survey results shown on row 9. This has =INDEX($B$3:$C$8,MATCH(B$10,$B$3:$B$8,0),2) in cell B9 as the code to reference the question to the domain. This is immediately above the questions in the example, but you can put it on a separate sheet if needed.
Then you can just sum them up.
=SUMPRODUCT(SUMIFS(INDIRECT(MATCH($E3,$A:$A,0)&":"&MATCH($E3,$A:$A,0)),$9:$9,F$2))
This formula uses MATCH, which returns an integer, inside INDIRECT to be used as a dynamic row reference. This will fail if the participant names are not unique. The SUMIFS inside the SUMPRODUCT allows the row to be treated like an array without using an array formula. So you can recreate the example I have and copy/paste or drag and paste the formulas as you wish.
A different approach may be that you want to sum up the points to the questions first and then do the conversion from question to domain. That way you don't ever have to manipulate the raw data, just the reports. That may be the better approach for you, actually.
Edit: Added information about the formulas and the example.
