20,754 Pointsconsole error: ReferenceError: taskListItem is not defined
Basically I'm asking if I missed something in the instructions. I did a search of my workspace code and only returned taskListItem in this function:
var bindTaskEvents = function(taskListItem, checkBoxEventHandler) {
console.log("Bind list item events");
// select taskListItem's children
var checkBox = taskListItem.querySelector("input[type=checkbox]");
var editButton = taskListItem.querySelector("button.edit");
var deleteButton = taskListItem.querySelector("button.delete");
...}
So taskListItem is a variable that should have been declared globally? Am I missing something?

Take a look at the last loop of the program:
for (var i = 0; i < incompleteTasksHolder.children.length; i++) {
// bind events to list item's children (task incomplete)
bindTaskEvents(completedTasksHolder.children[i], taskIncomplete);
}
Notice that the loop is passing the children of completedTasksHolder to bindTaskEvents one at a time, but the loop itself is using the number of children of incompleteTasksHolder as it's limit. So unless both lists have exactly the same number of children, this loop will run too few or too many (where some will be "not defined") times.
