Trying to position player

Hi
Overall I think the player is very easy to use. It took me less than 5 minutes to download, install and put a mp3 on my page.

My problem is that I am trying to place the player inside a div. I want it centered right below the title. It shows up outside of the div, top left of the page. Of course, I have placed it between my div tags, but beyond that, I am at a loss.

I know a bit of HTML and CSS, enough so that I can look stuff up and follow instructions, but no PHP, to give you an idea of my level of experience.

I would share the page, but it is not published as it is for a professional site and I don’t want to show it until it is right.

Thanks
