When I run the following HTML page in the Google Chrome Browser via Netbeans, I am met with this error (see Title) when I try to select a person from the list.
xmlhttp.onreadystatechange = function()
This line of code and the one below seems to be the areas of concern based on Chrome's Developer tools.
select name="users" onchange="showUser(this.value)
Can anyone pinpoint what needs to be changed?
