title: SSRS date default with formula disables parameter
body: <p>When I set a default value formula for a date parameter in SSRS, such as:</p>
  
  <pre><code>=CDate(”01/” &amp; Month(Now) &amp; “/” &amp; Year(Now))
  </code></pre>
  
  <p>or even:</p>
  
  <pre><code>=Now
  </code></pre>
  
  <p>the date parameter control becomes disabled with nothing in it. Does anyone know what simple thing (I am sure) I am doing wrong?</p>
