I want each text field to show a message in cart page when a customer type in a text.

      <input name="words1" rows="4" cols="40"
       onkeyup="return check_length(this, words2, words3, words4)">
      Word count: <span id="words1_count">0</span>
      <input name="words2" rows="4" cols="40"
       onkeyup="return check_length(this, words1, words3, words4)">
      Word count: <span id="words2_count">0</span>
      <input name="words3" rows="4" cols="40"
       onkeyup="return check_length(this, words1, words2, words4)">
      Word count: <span id="words3_count">0</span>
      <input name="words4" rows="4" cols="40"
       onkeyup="return check_length(this, words1, words2, words3)">
      Word count: <span id="words4_count">0</span>
      Words remaining: <span id="words_remaining">400</span>
