title: Copy every row of Data from one sheet that has a given value in column K to another sheet
body: <p>I'm working on a Google Spreadsheet the will use a Script to copy every row of Data from one sheet that has "Done In The Past 30 Days" in column K to another sheet.</p>
  
  <p>By "sheet" I mean every tab.
  Source tab is "Arley" destination tab is currently "ArleysSandbox"
  Every row has ll columns, A-K. The entire row should be carried over.
  The number of total rows in the sheet will increase over time.
  Every time I run the Script, I want it to clear all existing data on "ArleysSandbox" first.
  Column K, where it says "Done In Past 30 Days" is a formula.
  I will eventually want to pull from multiple sheets and compile on the Sandbox sheet. </p>
  
  <p>I was using a post from the old forum as a starting point but got stuck due to my lack of knowledge. <a href="http://productforums.google.com/forum/#!msg/apps-script/FNGzVkEqZh4/x8WCYtjvpI8J" rel="nofollow">http://productforums.google.com/forum/#!msg/apps-script/FNGzVkEqZh4/x8WCYtjvpI8J</a> Thanks in advance for any suggestions.</p>
