UnitBuff

Hello,

For the first attempt of making a simple addon for wow I tried to make a wintergrasp addon. However I seem to fail to understand the LUA error reporting.

This is the error I get in-game:

Message: Interface\AddOns\wg\wg.lua:15: Usage: UnitBuff("unit", [index] or ["name", "rank"][, "filter"])
Time: 06/01/10 20:46:43
Count: 1
Stack: [C]: in function `UnitBuff'
Interface\AddOns\wg\wg.lua:15: in function `value'
Interface\FrameXML\ChatFrame.lua:3577: in function <Interface\FrameXML\ChatFrame.lua:3509>
[C]: in function `ChatEdit_ParseText'
Interface\FrameXML\ChatFrame.lua:3222: in function `ChatEdit_SendText'
Interface\FrameXML\ChatFrame.lua:3246: in function `ChatEdit_OnEnterPressed'
[string "*:OnEnterPressed"]:1: in function <[string "*:OnEnterPressed"]:1>

Locals: (*temporary) = "player"
(*temporary) = nil

Now my question is how to read those errors and do the debugging.

Thanks in advance

This is the problem in ur Lua code. shows the line and location and whats wrong with it. in this case ur not using UnitBuff properly.

Locals: (*temporary) = "player"
(*temporary) = nil

looks like u've manage to include the first argument of the function but theres something going in the second argument. ((someone correct me if im wrong))

I am currently doing this:

if(UnitBuff("player",WG_BUFFNAME))then <- line 15
//do something
else
//do something else
end
