Hi Saumitra,
Is this a single row collection? If so, then try transposing the collection first - an action for this is available in the Collection Manipulation utility object. You will then have a Name/Value pair collection which you can loop through to check for "O" in the Value column and then read what is in the corresponding Name column.
Regards,
Jared
