title: Error when I convert to string value in Report Designer
body: <p>This has got to be simple but I cannot find an answer anywhere.</p>
  
  <p>I'm using Report Designer 2012, running local IIS and WebViewer.  The report works just fine outputting the data form the database just like I'd expect until I get to the summary.The report begins with a summary page and is followed with a list for subsequent pages.  </p>
  
  <p>I can successfully output expressions like <code>=(2+3), =Code.ConcateString("val1", "val2") and =First(Fields!first_name.Value, "CallLog")</code></p>
  
  <p>Anything like this fails: </p>
  
  <pre><code>=First(Fields!first_name.Value, "CallLog") &amp; " test"
  
  =Code.MyMethod(First(Fields!first_name.Value, "CallLog"))
  
  =CStr(First(Fields!first_name.Value, "CallLog"))
  </code></pre>
  
  <p>So I think I've narrowed the obscure #ERROR tag to it having something to do with the string conversion.</p>
  
  <p>My end goal is to simply output <code>(Fields!first_name.Value, "CallLog")</code> and <code>(Fields!last_name.Value, "CallLog")</code> to a single textbox.</p>
