In many reports, we may need to show some total information: sum of the group, number of rows in the list, and many others. FastReport uses totals to perform this task. For the total, you need to indicate the following parameters:
| • | The total function type; |
| • | The expression, which is supposed to be calculated. For the "Count" function, you do not need to indicate the expression; |
| • | The condition. The function will be calculated if the condition is met. It's not obligatory to set up the condition. |
| • | The data band, for which the function will be processed; |
| • | The band, in which the total value will be printed. |
The list of total functions is given below:
