We are going to try something else, can you update the hintstrings like I did here below? Don't use '&' for now, just follow this.

I think that it has something todo with the trigger, if the string cannot be found you will get something like: 'undefined string'.
That is here not the case.
 
If you're wondering how you probably setup this you can look at these screenshots.

The problem is that the flogger file is not loaded inside your mod.
 
You need to do the following:
 

 
Initialize the .gsc file via MAPNAME.gsc
