Defining expression quotas
1 Choose the Expression Quotas tab.

3 Define the quota characteristics and selection criteria as described in the following topics:
Categorical variables
Numeric variables
Text variables
Boolean variables
4 If the expression is based on two or more variables or values, click Next, otherwise click Finish to close the dialog box. See Expression quotas using two or more variables.
The quota appears on the Expression Quotas tab with a unique name and a default target of 100.

6 In Type, choose one of the following from the list:
Option
Description
Normal
This is an ordinary quota, so the sum of pending and completed interviews for this quota must never exceed the target. Once the sum of pending and completed interviews for this quota matches the target, all subsequent interviews for this quota will fail. If any of the pending interviews do not complete, further interviews will be required to meet the target.
Allow over
Allow the sum of pending and completed interviews for this quota to exceed the target. New interviews may be started for this quota until the number of completed interviews matches the target. If all the pending interviews complete, the target may be exceeded. Once the target has been met, any new interviews for this quota will fail the quota test and will be dealt with as specified by the scriptwriter (usually the interview terminates).
Counter
There is no target for this quota so there will be no quota control, but the number of respondents belonging to the quota will be counted.
7 In Description, type a short description of the expression.
8 To save the definition choose File > Save.
Note You must give the .mqd file the same name as the project and save it in the project’s source directory otherwise the activation process will fail when the scriptwriter tries to activate the project.
