Gmod - Custom Models ERROR

So, I am trying to use custom models, I have it inside the Fast DL but only I can see it,
My friends get this:

I’m not sure what I need to give you but I follow

I am using Deathrun instead of Dark RP, I don’t think it makes a difference.
Help?

EDIT:
Some players say they can see the model.

Did you do:

if (SERVER) then
resource.AddFile(“model/foldername/modelname.mdl”)
end

so clients download the model?

Were do I put it ._.
Sorry, My setup is

go to this
gmodserverroot/lua/autorun
create fastdl.lua
and add [lua] if (SERVER) then
resource.AddFile(“model/foldername/modelname.mdl”)
end [/lua]

Fixed thanks

A quick question. I’m relatively new to the forums and I don’t know how to use the code box for posting lua in a reply. How do you do it? Please don’t flame me for being a nub! o_o

Either [ code]


 tags or [ lua][/lua] tags
