# sum returns name

Hi, I followed this documentation to get the sum of a column and the result cell return #NAME after I press "apply". How can I get the sum please ?

Thanks

LBO : 6.2.7.1

**Edit :** Sorry : I forgot to give the link to doc.
The formula is =sum

I have a question I want to add : do ALL the cells selected MUST have a number in it ? Column is a match to a calendar column and not all days are defined yet.

Please add at least your formula - otherwise the only advice that can be given is to read the Error Code Page - Scroll down to 525.

regarding your "Answer:

`=sum`

isn't a valid formula. You don't tell the command (sum), which cells to sum. So it should look like`=SUM(A1:A10)`

, if you want to sum values in from cell`A1`

through cell`A10`

Ok I got it : press sum not write it.. Sorry I need sleep ! ^^ Thanks !
