Hi Customer, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. Can you send me a copy or a dummy of your problem Excel file where this problem is happening so that I can check it on my PC? You can delete sensitive information before adding the file here in your reply or in attaching it in your reply.
Please let me know by replying to me here so that I can help you further.
Thank you for the test or sample files. Please give me a moment to check it.
Thank you for patiently waiting. I just fixed the problem on this particular sample file. It appears that the sheet names have special characters or hidden characters that caused the 3D sum or 3 dimensional sum formula to fail.
In order to fix your issue, the sheet range needs to be enclosed with single quotes, like:
I created sample sheets and the format sum(sheet1:sheet2!A1) works fine. So I believe the problem is with the named sheets that you have. I believe these sheets are created by other programs and not created manually so that explains why the naming has issues.
Here is the attached fixed file:
Another thing that can surely help you in your 3D sum formula is by using wildcards. In your sample file, you can enter the formula:
And when you press Enter, Excel will build the correct formula for you. This works ONLY if the names of the sheets are in continuous numbering like your, N75736 and N75737.
