title: An attempt was made to set a report parameter 'studentSignDateParameter' that is not defined in this report

  <p>The parameters are set from the controller as seen above.</p>

  <p>I've added all the parameters in my report data and everything else works, but not the 'studentSignDateParameter'.</p>

  <p>tried to specify from the parameter's proprieties that it is a date but I get the same result. "companySignDateParameter" works just fine and it is a string of a date.</p>
  
  <p>I've also tried giving the parameter a random value, a string or whatever and still this error persists. I don't think it has to do with the code, as Visual Studio detects no errors.</p>
  
  <p>Any ideas? what could possibly the problem with that parameter? I've deleted it and remade it but nothing changes. </p>
