Sidebar not working

[Kristienne66]

Here's my code

on join:
while player is online:
wipe player's sidebar
set name of sidebar of player to "&2&Skyblock"
set score "&7&m----------------" in sidebar of player to 10
set score "&7&lYour Stats" in sidebar of player to 9
set score " Cash: &6{cash::%player's uuid%}" in sidebar of player to 8
set score " Bank: &6{bank::%player's uuid%}" in sidebar of player to 7
set score " Level: &6{level::%player's uuid%}" in sidebar of player to 6
set score "" in sidebar of player to 5
set score "&7&lLocation" in sidebar of player to 4
set score " " in sidebar of player to 3
set score "" in sidebar of player to 2
set score "&7&m----------------" in sidebar of player to 1
wait a second

But then it says that it can't understand this condition/effect for lines 3 to 14. I'm in 1.20.4 Java edition.

every 1 second:
loop all players:
set title of loop-player's scoreboard to "servername"
set line 4 of loop-player's scoreboard to "&7Player: %loop-player%"
set line 3 of loop-player's scoreboard to "Server Ip: "
set line 2 of loop-player's scoreboard to "Money:"
