title: Check if a range of cells has any number bigger or smaller than 0
body: <p>Is there a way to identify in column L if any of the cells between C and K contain a number greater or smaller than zero?  </p>
  
  <p>If yes it should return TRUE if not it should return FALSE. So in the example picture rows number 4 and 6 should return FALSE and rows number 1,2,5 should return TRUE.  </p>
