Hi, I'm working on a school project atm where I have to access a database and put that on a website

I coded the thing and it didn't work so I started debugging, and now I'm left with only these lines of codes

use DBI;
print "content-type: text/html \n\n";
print "abc";

Thie should just display "abc" on the screen right?

but I'm getting a blank page. According to my previous experience, this means that there's error in the code right? but that means the only thing could be wrong is "use DBI";

What's wrong with that? the server hosting company claims that they have it installed

please leave your opinions here, I really need them, even if you think I'm right cuz then I can take these and ask for further assistance.

Thank you.
