Another option would be to ask your teacher what s/he'd recommend.

If you either already have or don't want to, some useful reading:

• Spreadsheet::ParseExcel
• CGI

The above modules are all you need to make what you want happen. Below are modules that can make your life easier ... if you're into that sort of thing

• HTML::Template / Template
• DBD::Excel (Of course, this means you have to use DBI and learn SQL, but your spreadsheet looks like it would meet the criteria for DBD::Excel ...)
• Win32::OLE

Now, it sounds like you have another issue - you don't know what you want done. Well, you know what you need to have done, but you don't know how to do it. This isn't a Perl issue or a web issue - it's a thinking issue. Unless you are willing and able to think, you cannot program. Period.

You have all the pieces, but I will bet you haven't put together a simple flowchart. You haven't laid out the sequence of events that need to occur in order to make this happen. You may not know the sequence of events. (Learn about how CGI works. Note - Perl and CGI are not the same thing. Perl does CGI, but so do a ton of other languages. For example, C++ does CGI on Unix quite nicely!)

Once you have laid out the sequence of events and have learned how your tools work, then you are able to build what you're looking to do. Of course, if you waited until the last minute, you're up a creek without a paddle. Good luck!
