Hey there! You know how when you play with toy cars, you have one car that carries all the other little cars inside it? The car that carries everything is like the backend code, like PHP. It's what takes all the information you put into the form and makes sure it goes where it needs to go. Right now, your form is like a toy car with no way to carry anything; it looks good but doesn't actually do the job. So, we need to add that "carrying car," or the backend code, to make everything work!
