table name is responsetable

columns/variables are rsq01,rsq02 etc etc

the values in these columns range from 0-5.

I have a separate crosstabe for each column.

I can't seem to figure out what I need to do for each cross tab to eliminate it reading in the value 0.

do i need to create an sql expression for rsq01 then use it in the crosstab and what would an example of that expression be?
