title: Customize "Add New Item" form in a Sharepoint 2013 List to pull parameters from the query string
body: <p>I would like to customize the add new item form in a sharepoint list to pull a query string parameter and automatically set it as one of the lookup fields in the new item. I have found a perfect tutorial (<a href="http://www.codeproject.com/Articles/194253/How-to-Customize-the-New-Item-form-to-take-paramet" rel="nofollow">http://www.codeproject.com/Articles/194253/How-to-Customize-the-New-Item-form-to-take-paramet</a>) for how to do this in Sharepoint Designer 2010 in Sharepoint 2010 but design mode was removed Designer in 2013 so that tutorial is not of much use.</p>
  
  <p>So basically what I'm asking is how do I do pull query string values in Sharepoint Designer 2013?</p>
