Hi I have a spreadsheet whereby I need to add numbers together from 2 areas.
A1: 1171
A2: 4202
A3: 1698
A4: 2801
A5: 4146
A6: 5100
A7: 5000
A8: 4287
A9: 4405
I want to enter a formula into A11 that allows me to add cells A1:A3 and A7:A9.
I have entered the following formula but get value# error:
=sum(A1:A3)+(A7:A9)
Sorry but my excel is not very good.
Thank you in advance for your help.
