Sum worker hours by last name only

Hi and welcome to the forum

Pictures are of little value. Honestly, no one wants to re-type your data to try and solve your issue. Additionally, we would only be guessing at how your data was structured, ie. formulas, formatting, etc. Additionally, due to how some browsers behave, many of our members cannot see uploaded pictures/images. Please do not take this route.

Please attach a sample file that represents what you have. The structure of your attachment should be the same structure as your actual data. Any proprietary information should be changed.

Include in the attachment any code you're currently using (whether it works or not) and an "After" of what you wish the output to be.

To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.

I don't know why, but tonight I am in the mood to re-type your data)), So try this:
Hours: =SUMPRODUCT(N(LEN(TRIM(RIGHTB(SUBSTITUTE($A$2:$A$40;" ";REPT(" ";99));50)))=2);$B$2:$B$40)
Workers: =SUMPRODUCT(N(LEN(TRIM(RIGHTB(SUBSTITUTE($A$2:$A$40;" ";REPT(" ";99));50)))=2))

Since Strogg was willing to do the heavy lifting, I have proposed an alternative solution using Power Query.

Power Query is a free AddIn for Excel 2010 and 2013, and is built-in functionality from Excel 2016 onwards (where it is referred to as "Get & Transform Data").

It is a powerful yet simple way of getting, changing and using data from a broad variety of sources, creating steps which may be easily repeated and refreshed. I strongly recommend learning how to use Power Query - it's among the most powerful functionalities of Excel.

- Follow this link for a video which demonstrates how to use Power Query code provided.

Here is an updated spreadsheet using the same concept only offering a dynamic parameter that lets you select the number of letters in the last name. Instruction on how to use are in the spreadsheet.
