Checkbox Check in a report

I am new user and currently I am requested to post a report with <b>selectable few checkbox display horizontally in the same line in a standard report</b>. And I am able to display them through looping by setting the position for each loop.

However, I am having problem when I want to detect the checking checkbox in the report for further processing. I am not sure <b>how to check the particular checkbox that i want as all my checkbox name are the same</b> ( from an internal table field ).

I really hope that someone can solve my problem. Thanks for your time and help. Please contact me for any doubts thanks.
