Hi
I have 3 columns in RS, 2 are reading from a SharePoint list and they are both Time columns, the 3rd column is a duration (calculated column in SP) which works fine in the RS report.
What I now want to do is add a 4th column in RS which adds up (sum) all of the duration but I keep getting errors about not being allowed to have aggregate unless it's in a header or footer - I've tried adding to both and I get a similar error again.
Any ideas how I can get this total column? I've tried creating a new dataset for it and also a textbox on it's own to display and it still doesn't work. I tried referencing ReportItems!TextBoxXX.value in the sum but no joy.
Thanks
