SIMATIC WinCC Flexible Smartserver/MiniWeb

I used to have a SmartServer/Miniweb on remote PC. In HTML pages, I used variables from WinnCC "Tags" directory, and I had no problems. Example, "Variable1" from "Tags" directory.

But now, I have some variables in subdirectory of "Tag" directory. Example, "Variable2" in subdirectory Tags/TagGroup. I tried to use "TagGroup\Variable2" in HTML page, but I got a ScriptError.



How can I access such variable (in subdirectory) from HTML page?



Thanks!
