Weirdest problem using extracted data

Dear All:

I've successfully extracted data from a URL, but now I am trying to pass it as a parameter to another URL, but instead of the value I am getting: com.screenscraper.common.DataSet@1031b7c (1031b7c is different every time, I suspect it's a memory location.

What am I doing wrong. Below is the log, I just used Google as the next URL for simplicity.

Any help is greatly appreciated.
