[css-d] nth of type issue

[Tom Livingston]

Having an apparent mental block.

Here's my structure:

<div class="content-wrapper container main">
     <div class="page-wrapper sitemap-page ">
          <div class="page-header-wrapper gdl-border-x bottom">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
          </div>
     </div>
</div>

And the selector I am using is:

.content-wrapper .physician_detail:nth-of-type(3n+4){
     clear:left;
}

What I want is:

<div class="content-wrapper container main">
     <div class="page-wrapper sitemap-page ">
          <div class="page-header-wrapper gdl-border-x bottom">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail"> <--- this gets clear:
left; to start new row of 3
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail"> <--- this gets clear:
left; to start new row of 3
               <div class="physician_detail">
               <div class="physician_detail">
               <div class="physician_detail"> <--- this gets clear:
left; to start new row of 3
               <div class="physician_detail">
               <div class="physician_detail">
          </div>
     </div>
</div>

My selector is close but it's clearing .physician_detail #3 and not #4
but then all seem to be getting cleared correctly. Variations of the
equation i've tried aren't working.

What am I not grasping?

Thanks for your time.
