title: SSRS 2016 IIF statement for font color not working in header
body: <p>I have a couple reports that allow the user to change font colors with a parameter selection, this is the expression in the font color attribute:</p>
  
  <pre><code>=IIF(Parameters!Display.Value = true, "#000000", "#ffffff")
  </code></pre>
  
  <p>We just moved reports to a new 2016 instance and this expression is no longer working in the header.  It works fine for all the fields in the table / body of the report.  </p>
  
  <p>UPDATE:  I have tried using the colors names (black/white) but no difference.  The colors are correct when exported or printed, it is just the initial display of the report after clicking "run" that is showing the wrong colors.</p>
  
  <p>UPDATE 2:  I have found an error - CSS3111: @font-face encountered unknown error. in File: powerbiglyphs-regular.eot</p>
  
  <p>UPDATE 3: I opened the report in chrome and used the dev tools to poke around inside.  I found this in a css file:</p>
  
  <pre><code>@font-face {
      font-family: "PowerBIGlyphs-regular";
      src: url("../fonts/powerbiglyphs-regular.eot");
      src: url("../fonts/powerbiglyphs-regular.eot?#iefix") format("embedded-opentype"),
           url("../fonts/powerbiglyphs-regular.woff") format("woff"),
           url("../fonts/powerbiglyphs-regular.ttf") format("truetype"),
           url("../fonts/powerbiglyphs-regular.svg#PowerBIGlyphs-regular") format("svg");
      font-weight: 400;
      font-style: normal;
      font-stretch: normal;
  }
  </code></pre>
  
  <p>But the only file in the FONT folder is fonts/powerbiglyphs-regular.woff.  Is it possible I am getting the error due to missing font files?</p>
  
  <p>Is there some quirk to 2016 that we need to know?</p>
