title: Crystal report formula workshop simple if not working
body: <p>I have to make a simple change to a report done by another developer and if I edit the "ShowAverageSpeed" formula in VS2010 I can see the formula as:
  if ({AXMXmlJob.AverageSpeed} = 0 ) Then "Stopped" Else  "Moving"</p>
  
  <p>I save the formula in the Formula Workshop but when I try to view the report on the website I get: "A string is required here."</p>
  
  <p>If I remove this from the report it renders fine so I am sure this is where the error is. AXMXmlJob.AverageSpeed is nvarchar(50) null but if I try to use if ({AXMXmlJob.AverageSpeed} = "0" ) the it complains that it is expecting a number? </p>
