I would like to make use of this feature but am baffled at almost the first hurdle.
Creating the Dashboard is easy but I cannot seem to do anything with Widgets.
I go 'Add Widget' then select 'Aggregation' and select the library that I want to use.
I get a message to say that 'This library does not contain aggregation functions.'
I have checked the library and it does have one entry in the Aggregation tab and the results show correctly in the List View screen.
So what obvious thing have I missed?
Thanks as always
