Help with scoreboard

[WampaKenobi]

I've made a small scoreboard skript but nothing shows up?
No errors when reloading skript but nothing happens :/
Any ideas ?
Version 1.8.8 all plugins are working.

Skript:

every 30 ticks:
loop all players:
wipe loop-player's sidebar
set name of sidebar of loop-player to "&c&lGain &4&lPrison"
set score "&a&3&l" in sidebar of loop-player to 15
set score "&cRank:" in sidebar of loop-player to 14
if loop-player do not have permission "scoreboard.premium":
set {_prefix} to "%colored loop-player's prefix%"
replace all "[" with "" in {_prefix}
replace all "]" with "" in {_prefix}
set score " %{_prefix}%" in sidebar of loop-player to 13
if loop-player has permission "scoreboard.premium2":
set {_prefix} to "%colored loop-player's prefix%"
replace all "[" with "" in {_prefix}
replace all "]" with "" in {_prefix}
set {_suffix} to "%colored loop-player's suffix%"
replace all "[" with "" in {_suffix}
replace all "]" with "" in {_suffix}
set score " %{_prefix}% &7+ %{_suffix}%" in sidebar of loop-player to 13
set score "&b&3&l" in sidebar of loop-player to 12
set score "&cMoney:" in sidebar of loop-player to 11
set score " &7%loop-player's money%" in sidebar of loop-player to 10
set score "&c&3&l" in sidebar of loop-player to 9
set score "&cOnline:" in sidebar of loop-player to 8
set score " &7%number of all players%&8/&7150" in sidebar of loop-player to 7
set score "&a&3&l" in sidebar of loop-player to 6
