Made A Mistake Posting?

I made a posting this morning. An update on what I thought was a previous posting by myself. A member pointed out it was not my original posting.

My question now is, (I hope this post is in the right place to ask my question, wasn't sure where to ask my question), can I add my posting this morning and add it on to the previous posting by another member or is this an error?

I had posted my image and question to the previous member's posting.

You can modify/delete all of your postings within a reasonable time frame. Send a NOTE TO STAFF if you can't get it to do what you want.

I think the edit limit is 24 hrs.
