[RMXP] guys this is pissin me off what do i do????

ok in my "bunch o addons script" theres this caterpillar part that allows you to have our party members following you,or come out of the main character like in the old school FF games,etc. anyways my prob is this


def update_buffer(next_move)
if next_move == nil
@members.each {|member| member.buffer = []}
else
@members.each {|member| member.update_buffer(
next_move == 'reset' ? nil : next_move)}
end
end


there is something wrong with this line

@members.each {|member| member.buffer = []}

and it keeps sayingscript 'bunch of addons' 2129:NoMethodError ocurred "underfined method 'each' for nil:Nil Class"


can someone help my prob?
