Where is the variable "node" you are referring to?

You have the right idea about adding a condition, but your test itself doesn't make sense. You haven't defined any variable "node", and even if you had, you cannot directly compare a single element to a collection of elements.

But the challenge only wants you to be sure you're acting on an INPUT element, so you could just compare that word with the target's tagName property.
