<p>I think you are confused between answering a question in a comment (50 rep) and answering as the site intends for everyone to be able to do (1 rep). This response was done in the text box below that you see as 'Your Answer' with several formatting options readily on display. This is where you should be able to provide answers even with only 1 rep. </p>

<p>It appears that what you are attempting to do is answer in a comment which is where I had previously answered you. This requires 50 reputation and is generally not supposed to be where an answer that is intended to be final or complete should go. </p>

<p>Providing answers in comments is for partial answers, asking for clarification, interrogatively arriving at answers, providing guesses and other interactions that are not explicitly intended to be fully authoritative. </p>

<p>Try providing your answer in the huge text box instead of a comment and it should work. Lastly, if the answer I have provided you here was helpful please check the check mark next to the answer.   </p>
