Make a cut of total an amount per day

[Cesar]

I need to do the following:
I have a DataSource with multiple columns, the column of interest is "amount".
I need to show the total amount in a day.
I have such amounts for every day 01-01-2013
before skipping the 02-01-2013
should show a line that says: Totals per day are: and the total amount in another text field just below the amount column.

How could i do that?

Hello,

Please try to add the grouping by day and calculate the sum by group.

Thank you.
