Example 6: Creating nets
Sometimes you may want to create net elements in a multiple response variable to show the number of respondents who chose one or more categories in a group of categories. In a single response variable a net is the same as a subtotal, which shows the number of responses.
You can create a net element anywhere in a categorical variable, however, they are generally placed immediately before or after the categories to which they refer. The following example creates a derived categorical variable based on the Remember multiple response variable.

The next topic,
Example 7: Adding categories to existing variables, shows you how to add categories to existing variables. You could use a similar technique to add nets to an existing variable.
