Error attempt to concatenate a user value?

[GameWalrus]

[lua]

function outputCurPos(ply)

ply:ChatPrint(""..ply:GetPos())

end

concommand.Add("outputCurPos",outputCurPos)

function outputHitPos(ply)

local playEye=ply:GetEyeTrace()
ply:ChatPrint(""..playEye.Entity:GetPos())

end

concommand.Add("outputHitPos",outputHitPos)

[/lua]

I get that error when I run either command, can someone please explain?

[lua]
function outputCurPos(ply)

ply:ChatPrint(""..tostring(ply:GetPos()))

end

concommand.Add("outputCurPos",outputCurPos)

function outputHitPos(ply)

local playEye=ply:GetEyeTrace()
ply:ChatPrint(""..tostring(playEye.Entity:GetPos()))

end

concommand.Add("outputHitPos",outputHitPos)

[/lua]
You may also want to check if the trace entity is valid,that's up to you.

There's some languages where that is required. I guess it confused him.
