How to choose different dataline in feeder

Hello All,
I have a query on passing parameters through feeder. I have 5 values in my csv file which acts as a feeder. If I want to validate the gatling for the third value, is there an option that I can use in the code to perform that.
At present, first value will be chosen as a part of validation. Please let me know if anyone has overcome this situation.

Thanks,
Sanjith
