It’s a very common requirement to have a ‘total’ row at the bottom of an applet displaying some quantities which displays the sum of all above rows. For instance, below you can see the total displayed of the revenue field.

It’s a simple 2 step process:

Step 1: Go to Object Explorer -> Applet-> List. Open the properties of List and Set these properties:

Total Displayed: TRUE
Total Required: TRUE

Step 2: Now Go to List-> List Column->Column whose sum is to be displayed(e.g. Revenue) and Set its Total Required property to be TRUE.

Now compile and check the UI. You’ll find the row displaying the total.
