Gemstone printer assistance

Hello I really need help with adding gemstone printers to my darkrp server. I did it on this one server that I use to have but now I just have no idea how. I use darkrpmodification and last time I put them into my server all I had to do was add their file to addons. EXCEPT I don’t know what that file was. I can’t find a download link for the printers and when I put the LUA of the gemstone printer addon (extracted with GMAD) into my addons folder nothing happens. I also have it force downloading on my server so that’s all good. I just don’t know what to do now. So if anyone has any advice or solutions please reply here, thanks.

Installation: http://pastebin.com/aaf7bt46

Ok so I did the installation guide but it did not work. I put this

[LUA]GM.Config.topazprintamount = 10
GM.Config.amethystprintamount = 15
GM.Config.emeraldprintamount = 25
GM.Config.rubyprintamount = 50
GM.Config.sapphireprintamount = 75[/LUA]

in settings.lua on line 260 and I put this

[LUA]DarkRP.createEntity(“Topaz Printer”, {
ent = “topaz_money_printer”,
model = “models/props_c17/consolebox01a.mdl”,
price = 1000,
max = 2,
cmd = “buytopazprinter”
})

DarkRP.createEntity(“Amethyst Printer”, {
ent = “amethyst_money_printer”,
model = “models/props_c17/consolebox01a.mdl”,
price = 1500,
max = 2,
cmd = “buyamethystprinter”
})

DarkRP.createEntity(“Emerald Printer”, {
ent = “emerald_money_printer”,
model = “models/props_c17/consolebox01a.mdl”,
price = 2500,
max = 2,
cmd = “buyemeraldprinter”
})

DarkRP.createEntity(“Ruby Printer”, {
ent = “ruby_money_printer”,
model = “models/props_c17/consolebox01a.mdl”,
price = 5000,
max = 2,
cmd = “buyrubyprinter”
})

DarkRP.createEntity(“Sapphire Printer”, {
ent = “sapphire_money_printer”,
model = “models/props_c17/consolebox01a.mdl”,
price = 7500,
max = 2,
cmd = “buysapphireprinter”
})[/LUA]

in entities.lua under the green line that says “Add entities under the following line”

but they still do not show up. I have no idea what to do at this point. So if anyone has any info on what i’m doing wrong I WOULD LOVE TO HEAR IT!
