There are two problems with your code! #1: you used document.getElementsById() instead of document.getElementById() ...the Element should not contain "s" since "Id" is singular not plural like "ClassName or TagName" #2 you must either add your function(s) inside the html element <script> tag or wrap all your function(s) up in "window.onload" since you wanted to get something out of the DOM or WINDOW ...heres a modified version of your code. https://code.sololearn.com/WsuM3dYda9TJ/?ref=app

So, "window.onload" is obligate, when we're working with DOM?

You need to put the part of your code where you collect the user input anf call the function red blue or green in a function. You then need to set that function equal to window.onload The cide fails because the FOM has not finished loading so document.getElementById("main") returns null.
