set {_npc} to a npc with name "%random player out of all players%" and entity type "PLAYER"

ERROR

'set {_npc} to a citizen with name "%random player out of all players%" and entity type "PLAYER"' is not a boolean (yes/no) (police.sk, line 840: set {_npc} to a citizen with name "%random player out of all players%" and entity type "PLAYER"')

plugins:
MundoSK, WildSkript, skDragon, SkQuery
Skellett, skRayFall, TuSKe Citizens

Can someone fix this error?
If it is impossible can someone tell me different way?
(I don't want to change my server version)

Have you enabled npcs in the skellett config file?

 

[Normalguy]

Yes

Try this:

set {_npc} to a npc with name "%random element out of all players%" and entity type "PLAYER"
