put your script in the html document using the <script> js <script> tag no need for using the window onload then

document.getElementsByClassName() returns an array of elements with such class name. To change the text of any element in the array, specify an index for it. Eg var payload = document.getElementsByClassName('row1') payload[0].innerHTML = 'text' Don't also forget to add window.onload = function (){ // Your Code }

The starter function makes sure that your DOM is fully setup or loaded before executing the JS code. Else your JS code will run without getting any element with the specified class name

You should add window.onload. You can see the code here https://code.sololearn.com/WXSa5gDVS8RG/?ref=app
