The function needs repair, the places where placeholder is used without quotes are erroneous. The repaired function would look like this:

function printNumber (number) { document.getElementById("placeholder").innerHTML = number; }

Once repaired, whatever you give as the parameter to that function will show up on the page as the content of the element with the ID placeholder.

Also note that despite the argument being named "number", the value passed to the function may or may not be an actual number (any string would do).
