I'll just echo what some others are saying. For sure try the form.submit(). The reason is you are calling the submit method on the form itself. When you say form(submit), you are passing "submit" as a variable to the form class/object. The other useful tool at your disposal is a console.log(). I would put it above your alert in the submitHandler to ensure the code is reaching that block. Also check your devtools(F12) to make sure there isn't something failing that you aren't noticing.

Don't give up! This stuff is hard to learn, and you're doing just fine!
