title: SSRS Expression error handling
body: <p>I am using the following expression in one of my report fields.</p>
  
  <p>=Fields!Value.Value*(Fields!DutyRate.Value/100)</p>
  
  <p>This works as exprected as long as there is a valid value in the Fields!DutyRate.Value.</p>
  
  <p>My problem is that the Fields!DutyRate.Value can contain non numerical values such as "Free".</p>
  
  <p>This means any rows with the word "Free" in them causes an #Error. This is OK as such but I would like to get SSRS to display something other than #Error. In fact I would like to to display "F" instead.</p>
  
  <p>Many thanks   </p>
