title: SSRS 2016 - cannot see parameter
body: <p>I am self-learning SSRS via Microsoft SQL Server Data Tools, VS 2015. I am using tutorial from <a href="https://www.youtube.com/watch?v=nBYn1DU3VMQ&amp;index=5&amp;list=PL7A29088C98E92D5F" rel="noreferrer">here</a></p>
  
  <p>I cannot see the parameter I created in preview. The visible has been selected in parameter properties. What have I missed out? Thanks in advance if anyone can help me.</p>
