Use the Filter on New Variable dialog to combine characteristics from multiple variables into a single expression. This dialog appears when you define a characteristic using a variable and then click Next. When you create an expression using multiple variables, you can combine the characteristics using either the And operator or the Or operator. For example, you could create a quota for respondents who drink Assam tea and who normally make tea using tea bags.

Choose the operator that you want to use to combine the quota characteristics.

Choose the variable that you want to add to the expression from the drop-down list.

Displays the variables and characteristics that you have chosen for the expression.
