The information in the game information section are not mapped to a variable therefore both methods you described fail. The first pattern you use is the inline text merging (meant for beginners) and fails silently.
The second method is the inline scripting form, meant for advanced users, and the message you see is it complaining that it can't find a variable in the global scope (integer, string or Boolean).
I'll expose this information via a special variable type in a later release For now, just ignore DRY, and repeat yourself.
