# 'Sum' function
The Sum function for a label or table cell allows you to collect data from different elements. This function allows you to perform a simple count of the number of items without having to use scripts.
To do this, go to the properties of a field in the Data section and select Summary. In the running field, you can choose to total only the group, the whole report or each page.
In the Run Editor (white box next to the summary) you can then select the function, i.e. whether you want the summary to be summed, counted (number) or other groupings.
Navigating to the Run Editor
Accessing the Expression Editor
Using respective formula fields (for example, “If output 0/1” (see formula below)), you can calculate characteristic values for elements.
{% code overflow="wrap" %}
```
Iif([LastExecutionStatusInvariant]=='Passed', 1, 0)
// all test cases with the status “Passed”
```
{% endcode %}
