title: Formula in Crystal report doesn't work
body: <p>I have below formula in my crystal report which doesn't work.</p>
  
  <pre><code>if({SINGLECASEMULTIPLEASSAY.sSampleName}="P")then
  val({SINGLECASEMULTIPLEASSAY.sODValue})
  </code></pre>
  
  <p>The output of the formula field is always 0.00 although the table SINGLECASEMULTIPLEASSAY has correct values. I also verified that table SINGLECASEMULTIPLEASSAY has valid data.</p>
