How do you create Scoreboards?

My code:

every second:
    loop all players:
        wipe loop-player's sidebar
        set name of sidebar of loop-player to "&b&lServer Name"

Errors on reload:

Line 13: Can't understand this condition/effect: wipe loop-player's sidebar (line 13: wipe loop-player's sidebar')

Line 11: There's no loop that matches 'loop-player to "&b&lServer Name"' (script.sk, line 11: set name of sidebar of loop-player to "&b&lServer Name"')
