Why is this tool script not working correctly?

This tool script is supposed to deploy an explosive strike on a position the user clicked. It works in solo mode, but when in server mode or online mode, it doesn't work at all, and I have no idea why, as output didn't give any feedback.

Can someone please help me?

Here's the script:

pospoints = script.Clicked.Value

local inactive = false

function roundedPos(pos)
    local x = math.floor(pos.x)
    local y = math.floor(pos.y)
    local z = math.floor(pos.z)

    return Vector3.new(x, y, z)
end

function b1(mouse)
m1 = mouse.Hit.p
pt1 = roundedPos(m1)
local e = Instance.new("Part")
local me = Instance.new("CylinderMesh")
me.Parent = e
e.Parent = game.Workspace
e.formFactor = "Custom"
e.Position = pt1
e.Size = Vector3.new(2, .2, 2)
e.BrickColor = BrickColor.New("Bright yellow")
e.Anchored = true
e.Transparency = .2
script.e1.Value = e
pospoints = 1
end

function b2(mouse)
local m2 = mouse.Hit.p
pt2 = roundedPos(m2)
local e = Instance.new("Part")
local me = Instance.new("CylinderMesh")
me.Parent = e
e.Parent = game.Workspace
e.formFactor = "Custom"
e.Position = pt2
e.Size = Vector3.new(2, .2, 2)
e.BrickColor = BrickColor.New("Bright yellow")
e.Anchored = true
e.Transparency = .2
script.e2.Value = e
pospoints = 2
end

function b3(mouse)
inactive = true
local m3 = mouse.Hit.p
pt3 = roundedPos(m3)
local e = Instance.new("Part")
local me = Instance.new("CylinderMesh")
me.Parent = e
e.Parent = game.Workspace
e.formFactor = "Custom"
e.Position = pt3
e.Size = Vector3.new(2, .2, 2)
