title: SSRS Passing values between list and subreport
body: <p>So this is like my third SSRS question and I've only been looking at it for a day :S</p>
  
  <p>This question may be a little sketchy as I'm still not up with the terminology.</p>
  
  <p>Basically I have a list that is bound to a "Select" of SiteId's. Inside this list I have a sub report. The idea is to pass these SiteId's into the sub report one at a time to generate a report for each site Id.</p>
  
  <p>But I can't figure out the expression required to pass this value in?</p>
  
  <p>Way off the mark? or is there an answer to this question</p>
