How Do You Animate A Sword?

Hey. The problem with my script is that the sword is not going up into idle mode after I use it to slash. I'll save you the time reading the whole thing. The only real relative lines are 4-8, 10-14 and 137-141. Please take a few minutes to comb through that and see what I did wrong if you think you could be of any assistance.

Sword = script.Parent:GetChildren()
Tool = script.Parent

function SwordSlash()
    Tool.GripForward = Vector3.new(0,0,1)
    Tool.GripRight = Vector3.new(0,-1,0)
    Tool.GripUp = Vector3.new(-1,0,0)
end

function SwordIdle()
    Tool.GripForward = Vector3.new(0, 0, -1)
    Tool.GripRight = Vector3.new(1, 0, 0)
    Tool.GripUp = Vector3.new(0, 1, 0)
end

Tool.BladePart.Touched:connect(function (hit)
    if not hit.Parent:FindFirstChild("Humanoid") then return end
    if hit.Parent.Name == script.Parent.Name then return end
    if not Tool.Active.Value == true then return end
    hit.Parent.Humanoid:TakeDamage(10)
end)

Tool.BladePart2.Touched:connect(function (hit)
    if not hit.Parent:FindFirstChild("Humanoid") then return end
    if hit.Parent.Name == script.Parent.Name then return end
    if not Tool.Active.Value == true then return end
    hit.Parent.Humanoid:TakeDamage(10)
end)
