GetTextSize Error

[wakeboarderCWB]

Sometimes I get this error, and sometimes I don't. The error is:

Hook 'DrawTime' Failed: lua\includes\modules\draw.lua:75: bad argument #1 to 'GetTextSize' (string expected, got nil)

Here is my code for the part of the HUD it's affecting:

[lua]local function TimerStatus()
timetowrite = "Round Finished"
end

usermessage.Hook("TimerStatus", TimerStatus)

function ReceiveTime( um )
roundtime = um:ReadShort()
timetowrite = "Time: " .. string.ToMinutesSeconds(tostring(roundtime))
end

usermessage.Hook("SendTime", ReceiveTime)

function DrawTime()
draw.SimpleText(timetowrite, "Bullet_HUD", ScrW() / 2, 20, Color(255, 0, 0, 255), TEXT_ALIGN_CENTER, TEXT_ALIGN_CENTER)
end

hook.Add("HUDPaint", "DrawTime", DrawTime)[/lua]

Anyone know why this is happening?

[lua]
local timetowrite = "Loading..."

local function TimerStatus()
timetowrite = "Round Finished"
end

usermessage.Hook("TimerStatus", TimerStatus)

function ReceiveTime( um )
roundtime = um:ReadShort()
timetowrite = "Time: " .. string.ToMinutesSeconds(tostring(roundtime))
end

usermessage.Hook("SendTime", ReceiveTime)

function DrawTime()
draw.SimpleText(timetowrite, "Bullet_HUD", ScrW() / 2, 20, Color(255, 0, 0, 255), TEXT_ALIGN_CENTER, TEXT_ALIGN_CENTER)
end

hook.Add("HUDPaint", "DrawTime", DrawTime)
[/lua]

Before you receive one of those usermessages, timetowrite doesn't exist. Try giving it a blank initial value by putting

timetowrite = ""

outside any function.

Oh, Ok. Thanks both of you.

Erm, it is not your code...
