Template talk:Xine/common

Help! Why did all use of '{{{frontend}}}' before my edit display 'xine' but now display '{{{frontend}}}'? to the bext of my understanding I didn't remove anything relating to setting a variable or something similar.

They didn't. You seem to be confusing what is rendered in the xine article on screen with what is displayed in the Xine/common template. The template "Xine/common" will always display '{{{frontend}}}'. Within the xine article, if you view the source code, you will observe that that template Xine/common is called, and that the value for frontend is set to xine.
