Tell Me When, Explosive Shot

Hi,

Im having trouble setting up Tellmewhen, to track my explosive shot procs. I set explosive shot for reactive ability and tick check activation border. Tried numerous conditions but I cant get it right.

Basically what I want is when lock and load procs, I want my icon on my tellmewhen bar to light up and if possible show charges on my explosive shot.

Spent alot of time trying to get it to work, so hopefully you guys are able to help me.

Thanks!
