as i can see that you put integer %f instead of integer %d or %i

on your sscanf it should be like this

pawn Code:

if(sscanf(params,"dd",id,time)) return SendClientMessage(playerid, 0xFF0000AA, "USAGE: /jail <playerid> <time> ");

AND

on your /jail string it should be like this

pawn Code:

format(str, sizeof(str), "Admin %s has put %s [ID:%d] in jail for %d minutes", admin, Jailed, id, time);
SendClientMessageToAll(COLOR_ORANGE, str);
