title: Dividing using nhibernate results in "Could not determine member from"
body: <p>This is probably something simple but I seem to be lacking some knowledge of how nhibernate works.  This is my code:</p>
  
  <pre><code>ICriteria query = Session.CreateCriteria&lt;TblProjectCategory&gt;();
  query = query.CreateCriteria&lt;TblProjectCategory&gt;(x =&gt; x.TblProjects)
      .Add&lt;TblProject&gt;(x =&gt; x.FldCurrentFunding != 0m)
      .Add&lt;TblProject&gt;(x =&gt; x.FldCurrentFunding / x.FldFundingGoal &gt;= .8m)
      .SetResultTransformer(
          new NHibernate.Transform.DistinctRootEntityResultTransformer());
  
  return query.List&lt;TblProjectCategory&gt;();
  </code></pre>
  
  <p>The resulting error I get is: "Could not determine member from (x.FldCurrentFunding / x.FldFundingGoal)"</p>
