Sum of columns until criteria is met, then adjacent cell continues until criteria is met a

Hi all,

I’m looking to automate a totals column for my spreadsheet and need a little guidance. I’m trying to get a cell at the far right of the sheet to provide a total of the cells within that row until a set criteria is met, the cell in the next column then needs to calculate the total until the criteria is met again and so on.

An image of what I’m trying to explain is below: (I have changed the information/style for confidential reasons)

The highlighted columns are where I need the calculations to take place.
The criteria is based on the comments for each build with calculations being made for builds if a possible 5 comments are present (in this example Cracked 1, cracked 2, cracked 3, cracked 4 and cracked 5).

The first product (ABC for this example) has ‘Cracked 2’ on the 2nd build, so the 1st and 2nd build hours need to be added together in ‘Total 1’ column (for this example it totals 195 hours).
The ‘total 2’ column then needs to calculate the next hours until the criteria is met again. For ABC this is on the 3rd build and so the total hours in ‘Total 2’ is 100 hours.


Currently the calculation is manually changed when new data is entered, but as we increase our products it is harder to track any changes and would make the process easier.

I’m not sure if this will be better with formulas in the sheet or with vba? If anybody could help, it is greatly appreciated.

Please let me know if you need any further information.

Thank you 

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.

This proposal employs multiple helper columns (U:AF) which may be moved and/or hidden for aesthetic purposes.
Columns U:Z are populated using:
