Edit theme for ad in pages

[Duken]

Hi,

I need to add a advertiment between the content of the article from pages an the reactions with "{advertisement="xxxx"}

Here: 

 

I can't find out what file i need to edit to add {advertisement="xxxx"} in the theme. It should be in the CMS content but i can't find it.

Could someone help me out and tell me what file needs to be edited? 

 

Regards,

ACP → Pages → Templates
It’s a Pages template, not a theme template. 

You can check in your Article database settings, which template is used for the record display.
