Help with simple JavaScript page for school? Please!
Hi guys, I’ve got an assignment due on Tuesday for a JavaScript class and as sad as it is I seem to be having some trouble with it…I think I have everything I need, but I’m probably not doing the syntax right or maybe I’m missing something completely. Here’s what I’m supposed to do (first two pages are instructions, last page is what it’s supposed to look like):

Here’s the code that I have, I’m only using an index and an external stylesheet. As I said I know I must be missing something or doing something wrong but for the life of me I can’t seem to figure it out…if anyone could help me out and tell me what part I’ve made a mistake in and maybe how to fix it I would greatly appreciate it! Thanks so much!

Enter your secret bonus code:

Stylesheet:
[CODE]div.title {
font-size: large;
font-weight: 800;
}
div.subtitle {
font-weight: 800;
}
div.centered {
text-align: center;
}
body {
font-size: small;
font-family: Verdana, Arial, Helvetica, sans-serif;
}
table {
font-size: small;
font-family: Verdana, Arial, Helvetica, sans-serif;
}
div#leftright {
text-align: right;
width: 100%;
overflow: hidden;
}
div.right {
float: right;
/*width: 100%;
text-align: right;
overflow: hidden;*/
}
div.left {
float: left;
/*width: 50%;*/
}
I’m not too worried about the stylesheet, it doesn’t have to look perfect…but for some reason it seems my functions aren’t working, and I’m not sure how I’m supposed to “add formatting to the courseInfo variable” and have it display both the course name and price.
Any help would be really appreciated!! ?
