Have a Set State action in a Workflow that’s triggered by a button click, create a custom state of a number type and in the Value box for the action have an expression for Do A Search For … for the data type, then select :each item’s amount and then select :sum (full expression = “Search For :each item’s amount :sum”). This will put the summed value into the custom state. Add a text box to the page that you want to display the value in and in the text box insert dynamic data and point it to the custom state (you’ll have to add a :formatted as).

Hope that helps.
