Switch statement issues

var i = 1; var listItem = "";

      switch (i) {
        // evaluates if the input items has reached/equals 5, returns message
        case i === 5:
          document.getElementById("resultsExpl").innerHTML = "Thanks for your suggestions.";
          break;
        // takes and processes user input
        default:
           var listItem = "item" + i;
           document.getElementById(listItem).innerHTML = 
           document.getElementById("toolBox").value;
           document.getElementById("toolBox").value = "";
           i += 1;
        break;
      }
  }

Need any assistance I can get. I am able to get the user input to print to the page just fine. The issue I am having is getting the first case's message ("Thanks for your suggestions") to print, once I have submitted 5 values.

The "case" statement takes just the term to be compared with the switch variable, an equality comparison is implicitly performed.

So instead of "i === 5" you would just put "5".

Thank you for your input.

I changed the code. I am able to get the message to populate, but now when I go to submit the 5th value... the message executes, however 5th value is never put in there with it

        switch (i) {
             // evaluates if the input items has reached/equals 5, returns message
             case 5:
                 document.getElementById("resultsExpl").innerHTML = "Thanks for your suggestions.";
                 break;
            // takes and processes user input
            default:
               var listItem = "item" + i;
               document.getElementById(listItem).innerHTML = document.getElementById("toolBox").value;
               document.getElementById("toolBox").value = "";
                i += 1;
                break;
          }

If you want both the case 5 code and the default code to run, remove the "break" between them.

Here is the HTML snippet that is being appended

  <article>
      <div id="results">

            <li id="item4"></li>
            <li id="item5"></li>
         </ul>
         <p id="resultsExpl"></p>
     </div>
     <form>
         <fieldset>
           <label for="toolBox" id="placeLabel">
             Type the name of a tool, then click Submit:
           </label>
           <input type="text" id="toolBox" />
