You can view any total for any column in the list.
To change a column to display the sum follow these steps:
Right click on the column header and select EDIT COLUMN from the pop-up menu.
Step 2. On the "Edit Column' window you will find a Math Function section. Change the dropdown to your desired type e.g. SUM.
Step 3. Click OK to close the window.
NOTE - You can change the color of the column by clicking on the COLOR button at the bottom of this window.
To display totals, the entire list must first be loaded into memory. When viewing a small list, this overhead is tiny. If you do have a list of hundreds or thousands Toolkit will present users with a progress bar as each row populates.
