[HELP] Gate Dosen't work

I've made a gate script works with bindKey...but i have to restart the script every join to make it work...if i'm in the server already i can't use it until i restart the gate..idk why ..no errors in debugscript too

    local gate = createObject (  980, 2287,603.20001220703,12.60000038147,0,0,0)

    local closing = false

    function MoveObject (thePlayer) 
        if open then -- Check is the gate is opened 
            return outputChatBox ("The Gate's Already Open", thePlayer, 0, 255, 0) 
        elseif closing then 
            return outputChatBox ("The Gate's closing", thePlayer, 0, 255, 0)
