Basically I have an imported spreadsheet in base with a query related to it that show name, date and total revenue. This is all in one row. For each sale I get I add another row or record. I would like to know if there is a way that I can run a function on multiple records in the query. I would like to sum the total sales revenue which is arranged like this.
Name Date Sales Rev
Mr A 12/12/12 £10
Mr B 13/12/12 £20
Mr C 14/12/12 £15
I would like to sum the Sales rev field in libre office base not calc.
