Hi @George_Marinos - Let's start with a dedicated thread and see how it goes. I've just created one here:
Could you please replicate your post in there, so we can get it going?
By the way, I've turned your snippet syntax into a dynamic snippet. You can do this by clicking in the "gear" icon at the far right of the editing menu at the top when your typing your post.
Then click "Text Blaze Snippet". You'll get a piece of code that looks like this:
[snippet]
Snippet contents.
[/snippet]
Just paste your snippet where it says Snippet contents.
Hope this helps
