Hi, Asya Kırkaya
Thank you for using Microsoft products and posting them to the community.
In the screenshot of your error, you are referencing what looks like a defined name, you can go to the formula-name manager to see if the name is there or if there is data under that name.
If it doesn't, it will report the error.
Then for more information, I may need to check and investigate your file, if it's convenient, could you share your file?
Why a sample file is important for troubleshooting. How to do it. - Microsoft Community
Looking forward to your reply.
Best wishes
