Error 'part is not a valid member of part'? [Solved]

so im getting this error that 'part is not a valid member of part' but im trying to disable a script and I don't know what it could be because im disabling the script not part and the Part.Script is a child of FireFountain I cheaked

local FireFountain = {
    F1 = script.Parent.FireFountain1,
    F2 = script.Parent.FireFountain2,
    F3 = script.Parent.FireFountain3,
    F4 = script.Parent.FireFountain4,
    F5 = script.Parent.FireFountain5,
    F6 = script.Parent.FireFountain6
}

local function EmitterActivate (EmitterNumber, IsActive)
    EmitterNumber.ParticleEmitter.Enabled = IsActive
    if IsActive == true then
        wait(0.1)
        EmitterNumber.Part.Script.Disabled = false
        EmitterNumber.FireBurningSoundEffect:Play()
    else if IsActive == false then
        EmitterNumber.FireBurningSoundEffect:Pause()
        EmitterNumber.Part.Script.Disabled = true
        end
    end
end

while true do
    EmitterActivate(FireFountain.F1, true)
    EmitterActivate(FireFountain.F3, true)
    EmitterActivate(FireFountain.F5, true)
    EmitterActivate(FireFountain.F2, false)
    EmitterActivate(FireFountain.F4, false)
    EmitterActivate(FireFountain.F6, false)
    wait(3)
    EmitterActivate(FireFountain.F2, true)
    EmitterActivate(FireFountain.F4, true)
    EmitterActivate(FireFountain.F6, true)
    EmitterActivate(FireFountain.F1, false)
    EmitterActivate(FireFountain.F3, false)
    EmitterActivate(FireFountain.F5, false)
    wait(3)
end
