Script Assertion

I have one Groovy Script & 2 Soap request -- for loop is written in groovy to iterate the data from excel sheet and then pass it to the first request, response of first request is being transferred to second Request and now, after execution with the second request I want to validate response with expected data (it is same which is coming from excel sheet and passed in first request too) in Script Assertion, on the basis of input (which comes from groovy for loop and same is being passed to first request as well). After that I want to place the TRUE/FALSE in the excel sheet on the basis of comparison result.

Kindly help me with same
