Sum differences in row values in Excel 2016

Hello,

I'm trying to show the total weight lost in a work group competition since the last weigh-in.

I cannot figure out how to add all of the weight lost by each individual without creating a column to do so.

I tried an array with ={X4:X35-K4:K35} which didn't give the correct value.

Sum differences between relative values of the above ranges without having to explicitly use =sum(x4-k4,x5-k5, etc). I hope this makes sense. I'm unable to post HTML code.

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a description 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 solution is 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.

If you use the evaluate formula feature on the formulas ribbon to step through the formula as it calculates, you will see what it is doing. It's a useful way of working out how these things do what they do.

Thank you. Sometimes the evaluate feature doesn't always help in explaining how a function works. I do often use the Formula wizard to build formulas and make sure i have the correct formula and it's doing what I want it to. I'll check out that link.
