# How to sum series of numbers in a single cell. MY Fx function doesn't do the job

=Sum(1.68,22.55) format doesn’t work in the cell. I downloaded most recent version of LIBRE. I used excel years ago. Am really stumped by this snag.

What do you get when using `=SUM(1.68,22.55)`? I do get `24.23`, which seems to be the correct result. Your usage may face two problem, but your detailed description (especially the resulting code in your cell) doesn’t allow to qualify.

Potential problem 1: Your settings (your locale) uses a comma as a decimal delimiter and the function argument separator is a semicolon `;` and thus your formula results in `#NAME!` - you’d need to use: `=SUM(1,68;22,55)` (Check `Tools -> Options -> LibreOffice Calc -> Category: Separators` which settings apply for your installation)

Potential problem 2: Your settings use local function names and again you get a `#NAME!` - that case you’d need to use the local name of the function `SUM` (e.g in German it would be: `SUMME`) or - what I would recommend - set option `Tools -> Options -> LibreOffice Calc -> Formula -> [x] Use English function names`

Anyway - see the answer of @blashrkh pointing to the spreadsheet way to handle this.

In order to maintain editability in excel you are better off enter numbers you want to calculate in a column and then calculating the sum using the range.

If you select a long range which includes blank cells (nothing entered in them), eg B4:B1000 then you can simply add each number by pressing enter. This works great for calculating a sum, but caution: this may affect more sophisticated calculations which rely on using #cells/#numbers (which in this case would be 1000-4=996).

This enables you to append to the list if you select a large range and the sum/total will update automatically if you change any of the numbers within the range.

1. select the cell where you want the sum/total to be displayed. eg, D4.
2. type =sum(
3. press and hold ctrl and select the start cell of the range, eg B4.
4. press and hold ctrl+shift to select the end of the range, eg, B9.

selecting the range with the mouse is easy but you can also by in the range manually by entering in =sum(B4:B9)

Yes, this should work fine. Are you getting an error message?
