The high school I work at has a cafe which trains students on creating menus and serving food.

Lately, I was asked if staff could enter orders online for the cafe.

So I created a bunch of forms for the teacher to enter all menu info, picture, prices.

Now, I am at the order form (

A "for" loop in PHP dynamically creates the number of items fields, so that the user can enter how many of each menu items they want.

How do I dynamically update the total field when the users enter a number? I created another "for" loop in javascript, but that didn't work.

Thank you in advance.
