Multiple crosshairs/cursors

Okay I’ve made this so far (see pics attached) and when the line traces it checks if the actor has a tag “enemy” which I have given to the turret. If yes then make crosshair red, otherwise it’s white. The problem is it is always white and the print string “enemy out of sight” is constantly checking even when I’m looking at the turret. Every time I play I get an error message though which I’m hoping is the reason it isn’t working, any ideas? Thanks for the help!
