I'm trying to recover the value of a Slidebar in order to activate a function with in parameters the value of this slidebar.
If you have an idea. Thank you !

init.lua
util.AddNetworkString("utilisationRadio")
util.AddNetworkString("receptionRadio")

function ENT:Use(activator, caller)
net.Start("utilisationRadio")
net.WriteEntity(self)
net.Send(activator)

end

net.Receive("receptionRadio", function()
print("test message")
local ent = net.ReadEntity()
ent:SetChannel(value)

end)

cl_init.lua
net.Receive("utilisationRadio", function()
local radioFrame = vgui.Create( "DFrame" )
radioFrame:SetTitle( "Choix du canal radio" )
radioFrame:SetSize( 300, 100 )
radioFrame:Center()
radioFrame:MakePopup()
radioFrame.Paint = function( self, w, h )
surface.SetDrawColor(0,0,0)
surface.DrawOutlinedRect(1, 1, w - 2, h - 2)

surface.SetDrawColor(60,60,60, 220)
surface.DrawRect(2, 2, w - 4, h - 4)
end

local radioSlider = vgui.Create( "Slider", radioFrame )
radioSlider:SetPos( 5, 23.5 )
radioSlider:SetWide( 300 )
radioSlider:SetMin( 1 )
radioSlider:SetMax( 100 )
radioSlider:SetValue( 1 )
radioSlider:SetDecimals( 0 )

local radioButton = vgui.Create( "DButton", radioFrame )
radioButton:SetText( "Se calibrer sur le bon canal radio" )
radioButton:SetSize( 260, 30 )
radioButton:SetPos( 20, 60 )
radioButton.Paint = function( self, w, h )
surface.SetDrawColor(0,0,0)
surface.DrawOutlinedRect(1, 1, w - 2, h - 2)

surface.SetDrawColor(200,200,200, 200)
surface.DrawRect(2, 2, w - 4, h - 4)
end
radioButton.DoClick = function()

local value = radioSlider:GetValue()

net.Start("receptionRadio")

net.SendToServer()

radioFrame:Close()

end

end)

So you need to write the value with one of the net.Write functions. Supposing this is an integer value it would be net.WriteInt(value, 32) as seen net.WriteInt or a float (decimal) value net.WriteFloat(value).
Reading the value would be the same but the net.Read functions and remember to read in the same order you write in.

Do not send the Player entity over a net.WriteEntity() instead use the built in argument of net.Receive on server (Refer to wiki)
so it would be something like this on the receive
net.Receive("receptionRadio", function(len, ply)
--blah blah
end)
