I am very new to PHP and somehow got thrown into an advanced level course. My instructor will not offer any help since it is an advanced course. I will post my code below in hopes that someone can at least point me in the right direction for a fix. This is only the first part of the assignment, but not worth going any further if I cannot get this part to work. I believe I have check all the braces and quotes, but I sure could have missed something or ?????.
