Your issue is that print returns true if the print succeeded. So rather than print "<b>Hello World</b>";, you probably just want "<b>Hello World</b>"; (or return "<b>Hello World</b>";), since subroutines return the last thing evaluated.

As a side note, this sounds like you are doing something imprudent, either from a security or reinventing the wheel perspective. This type of templating is natural in Template::Toolkit, and might be worth a perusal.
