Template talk:Links 1

Template Links 1 won't work for me. I simply copied the code for template Links 1 and template ! to my template, but I get strange stuff like this (the star is a littel box):

{{#if:|
    * [[{{{2}}}|{{{3}}}]]|
    * [[{{{2}}}]]}} 

eventhough it is a template and not supposed to show this. As a result it won't work on my mainpage.

Ok, I found it out by myself. Installing Extension ParserFunctions helps.
