woah thats messy . First tip if you double click a wire you can add reroute nodes this allows you to keep everything tidy.
Plus you should be using custom events or functions to hide most of the code that is not necessary to see
As for youre problem its hard to see with it set up as it is.
Only thing i can suggest is check that you are setting the attention variable properly and that it is being casted properly. Where you have the target/attention node right at the beggining drag out a print screen and attach it to press g. This should print out the value. Check this value first. If this is fine then you need to check where you are setting the value which im guessing is in youre first person character bp.
