[Solved] small leaderboard updating problem

[Damned Blade]

let's keep it simple. I want this to happen:

• Set Player_Kills[(Player number of (Owner of (Killing unit)))] = (Player_Kills[(Player number of (Owner of (Killing unit)))] + 1)

but whatever I do, I can't find/get the "+1"..
Heck, i followed the leaderboard tutorial here and on world-editor-tutorials step by step..
Did I do something wrong?
