title: Calculate certain # of business days from user entered date
body: <p>I'm working on a PDF where the user enteres a date in field "startdate."
  I need script to populate field "date1" with a new business date a specified number of days.</p>
  
  <p>For example:</p>
  
  <pre><code>User types 9/7/2012 in "startdate" field :: I need "date1" field to say 9/11"
  Note: this takes into account that 9/8 &amp; 9/9 are weekend dates.
  </code></pre>
  
  <p>I've been able to generate this in Excel using WORKINGDAYS formula, but need to get it to work in Adobe Acrobat. <br>I've got experience with form fields, but never been able to get them to calculate (aside from basic math).</p>
