Hi @Crystal Hurla,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your sharing, you are having syntax issue in your formula since Excel does not have a built-in function of SUMPRODUCTIFS.
If your goal is to calculate the sum of (I*L) divided by sum of I for rows where C="KS" and D="STEER", you can try this formula:
=SUMPRODUCT(($C$2:$C$141="KS")*($D$2:$D$141="STEER")*$I$2:$I$141*$L$2:$L$141)/SUMPRODUCT(($C$2:$C$141="KS")*($D$2:$D$141="STEER")*$I$2:$I$141)
You can try workaround and notify me whether it helps. If not, we can work together to find a solution.
I hope this information is helpful. If you have any questions or need more help, please feel free to share them in the comments. I will be happy to assist you further.
Thank you for your patience and understanding. I'm looking forward for your reply.
