<p>This sounds a lot like you are asking a duplicate of a closed question. If the question was closed because it's unclear, the best course of action is to have the OP refine their question sufficiently so that it may be reopened. (If the duplicate, closed question was off-topic or otherwise unsuitable it is not advisable to ask the same question again; it will simply be closed again for the same reason.)</p>

<p>In the interim, nothing stops you from asking the same question with a different title. If you find that it is difficult to come up with a title that is not already taken by an existing question, it's worth pausing to consider whether your question is a duplicate of any or all of <em>those</em> questions.</p>

<p>If the OP is not forthcoming about making edits, the question will eventually be deleted by automated cleanup scripts (affectionately called the "roomba"). Downvotes can accelerate that process. Once the closed question is deleted, this will make available the unique title that you desire.</p>
