Input not carrying over?

[NyeBlock]

I am fairly new to lua and I am not sure how to deal with the problem below. Any help is appreciated.
[lua]
--Code in the first net function
ipw = vgui.Create("DTextEntry",ip)
ipw:SetSize(490,230)
ipw:SetMultiline(true)
ipw:SetPos(5,30)
--function ipw:Paint(w,h) draw.RoundedBox(0,0,0,w,h,Color(0,0,0,200)) end
local ipwb = vgui.Create("DButton",ip)
ipwb:SetSize(100,30)
ipwb:SetPos(0,265)
ipwb:CenterHorizontal()
ipwb:SetText("")
ipwb.DoClick = function()
if ipw:GetValue() == "" then
LocalPlayer():ChatPrint(am.TextNoInput)
else
net.Start("preventmulti")
net.SendToServer()
net.Start("sendalert")
net.WriteString( ipw:GetValue() )
net.SendToServer()
ip:SetVisible(false)
end
end
function ipwb:Paint(w,h) draw.RoundedBox(0,0,0,w,h,Color(0,0,0,200)) end
local ipwbt = vgui.Create("DLabel",ipwb)
ipwbt:SetText("Send")
ipwbt:SizeToContents()
ipwbt:Center()
end)
--Code in the second using the DTextEntry in the first
local aptp = vgui.Create("RichText",ap)
aptp:SetSize(ap:GetWide()-10,90)
aptp:SetPos(5,30)
aptp:AppendText(ipw:GetValue()) --Line that the script error is referring to.

--Error I am getting
