title: The parameterized query expects the parameter ###### which was not supplied
body: <p>I am trying to run this code but I get the error "The parameterized query expects the parameter @faid which was not supplied". At least based on my knowledge, this code looks good. I am using VS 2010 on Windows 7 with SQLEXPRESS as backend.</p>
  
  <p>Thanks in advance.</p>
