Hi Hardeep,

I can definitely help you with that! It sounds like you have some extra spaces after your numbers in your Excel sheet, which is causing issues with your sum function. Here's how you can remove those spaces:

1. Select the column that contains the numbers with spaces.
2. Click on the "Data" tab in the ribbon at the top of the screen.
3. Click on "Text to Columns" in the "Data Tools" section.
4. In the "Convert Text to Columns Wizard" that pops up, select "Delimited" and click "Next."
5. In the next screen, make sure only "Space" is selected as the delimiter and click "Next."
6. In the final screen, make sure "General" is selected as the column data format and click "Finish."

This should remove any extra spaces from your numbers and allow you to use the sum function properly. Let me know if you have any other questions or if this solution worked for you!
