Edit Calculation

The process to edit a calculation in a test is available through the Calculations Tab of the Test Definitions Tab., which can be accessed through the Tests Window.

To edit a calculation:

Search for and select a test from the Select Test drop-down menu.
Right click on the calculation to be edited in the Calculations Table.
Select "Edit Calculation" in the context-sensitive menu.
- Users can also begin the process of editing a calculation by clicking on the calculation to be edited in the Calculations table. This will highlight the calculation, indicating that it has been selected.
- Users can then click on the Edit Button.

The Edit Calculation window is displayed.
- Edit the name and description as needed.
- Enter the calculation, including any mathematical operators ( such as (), /, +, -, and *) and/or excel formulas, and insert field variables where appropriate by clicking on the Insert button next to the desired field.
  - Users can insert variables from test questions using the Test Questions Tab and variables from mix designs using the Mix Design Variables tab.
- Click on the Save Button.

Test questions are assigned a variable letter for calculations according to the order in which they were added to the test. Changing the order in which questions appear in a test will not change variable letters.
Users are prevented from saving changes to a system item to which changes have already been made. This prevents concurrency errors.
