Can someone help me with a leaderboard problem please?

I have been trying all kinds of different code to get the leaderboard to compare the infamy from the killer to the guy that died.

but nothing I have tried is working.

right now I have 3 tabs.

kills, deaths, and infamy

when someone kills someone the program should compare the killers infamy with the one whom died and compare it to his own.

if the infamy.value is 0 it will add 100

if the infiny.value is less than the one who died it should take the infamy value from the one who died and times it by .5 and add that figure to the killers infamy.

but nothing is working. I cant figure out how to get the if statement to looking the other persons stats.

can someone help me please. this is the code that I am playing around with.
