title: Conditional formatting to show date task completed is in/out of target with icons
body: <p>apologies for asking a basic question.</p>
  
  <p>If cell A2 contains the dates a task should be completed by, and cell B2 contains the actual date completed. </p>
  
  <p>Can the icons be used to show a green tick next to the date (in B2) if it is = or &lt; A2 or a Red Cross if it's > than A2? </p>
  
  <p>Many thanks</p>
