You must assign a column to the Variables to standardize role.

Roles	Description
Roles
Variables to standardize	lists the numeric variables to be standardized.
Additional Roles
Frequency count	lists a numeric variable whose value represents the frequency of the observation. If you assign a variable to this role, the task assumes that each observation represents n observations, where n is the value of the frequency variable. If n is not an integer, SAS truncates it. If n is less than 1 or is missing, the observation is excluded from the analysis. The sum of the frequency variable represents the total number of observations.
Weight	specifies a numeric variable in the input data set with values that are used to weight each observation. These values can be nonintegers. An observation is used in the analysis only if the value of the Weight variable is greater than zero.
Group analysis by	enables you to obtain separate analyses of observations for each unique group.
