This question relates to JavaScript.

Could you please show me how to get my code below working. Please keep it simple.

The code has a green square image.  When it is clicked the function generates a random number from 1-3. If the number generated is '1' then the green square is replaced by a picture of a tree. Please keep it as simple as possible because I am new to coding. Thanks.

<head>

<script>
       var randNum;
       var but;
       var but1;
      
       //var imageArray = ["greenSq1","greenSq2","greenSq3"];
      

       /**
       * This function generates a random number between 1-3
       */
       function randFun1(){
           randNum = Math.floor(Math.random()*10);
           randNum = Math.round(randNum/3);
               if(randNum !=0){
                   rNum = randNum;
               }
                   if(rNum == 1){
                       document.getElementById("greenSq1").src = "tree";
                      
                   }
       }
      
</script>
</head>

<body>
       <img id="greenSq1" src="greenSquare.png" onClick="randFun1" style="width:100px;height:100px;visibility:visible"/>
       <img id="tree" src="tree.jpg" style="width:100px;height:100px;visibility:hidden"/>
