Please help with Dreamweaver problem...

Hello I am trying to get the 'addthis' button to appear in the following sidebar. All the CSS is set up correctly but as I am new to this I am having a problem ensuring that the 'add this button' appears in the same sidebar box as the contact details below. I should point out that I want it to appear in the sidebarlt box within the sidebar, as having it appear in the sidebar is not a problem. The problem is having it appear with the sidebarlt box below the contact details.

I hope I am making sense and that I have posted this in the correct forum but any assistance would be grately appreciated.

Code:

<p class="sidebarlt">Contact Details:<br />
First Recrutment (UK) Ltd<br />
