Thanks to Jim, Dale Jay for yours email.

I did overal chi-square test on the whole contingency table and it was significative. 
I want to do test with only one marginal variable because the researcher wants to know if there are differences 
among proportions of the levels of the second variable in each level of the first. This sound like pairwais comparations.

I tried to run separately for each row as suggested by Jay, but in the  output we have just
Column   Frequency   Percent   Cumulative Frequency   Cumulative Percent  
with the correctly calculated table, but no chi-square test.

In this mean time I found the Marascuillo procedure in the site: http://www.itl.nist.gov/div898/handbook/prc/section4/prc474.htm
and I would like to know if someone has worked with this test? References? It sound what I look for but I am not sure about this test.

Thanks
Carlos
