Question : Follow Up on previous question

Hi,

following up on the following question,concerning rows to columns transform,
http://www.experts-exchange.com/Database/DB2/Q_26406936.html
I could achieve what i wanted.But i have a problem arising here.
When the address is repeating for the same ID, the row_number function is returning 2 for that address and so, when i display as address1 and address2, the values are the same..

In short, what i want is that the addresses should not repeat even if they are repeating in the rows..
Same applies to the phone numbers and emails.

How can i do this? Please help.
