User blog:Penguin-Pal/Template Code issue

Hi everyone, and thanks for reading this!

I am having some troubles in another wiki, called the Commando 2 Wiki: It has no Ambox template, but the most important part is- that i tried to create a template based on Navbox, but it seems to be empty, although i compared it with similair templates, and i can't find the problem. If you'd take a look at the template and find the problem, please let me know, so i'll fix this.
