[Help Request] Mod is "Incompatible"

[Aboogabooga]

I'm currently trying to learn how to make mods. I made one (it's called "Looky"), but in-game (at the character select screen) it says that it's "Incompatible". Could somebody help me find the bug(s) in my code?

XML:

<Ui xmlns="http://www.blizzard.com/wow/ui/"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.blizzard.com/wow/ui/ ..FrameXMLUI.xsd">

<Script file="Looky.lua"/>

<Frame name="Looky_Frame">
<Anchors>
<Anchor point="CENTER"/>
</Anchors>
<Frames>
<Button name="Looky_Button">
<Scripts>
<OnClick>
Hearth()
</OnClick>
</Scripts>
<Anchors>
<Anchor point="CENTER"/>
</Anchors>
</Button>
</Frames>
</Frame>

</Ui>

LUA:

function Hearth()
UseContainerItem(0, 1[, 1);
end

TOC:

## Interface : 20400
## Name : Looky
## Notes : An addon to use the first item in your bag (usually Hearthstone) when the button is clicked.
## Author : MelonRind
Looky.xml
Looky.lua

Please don't tell me to look through other mods, I've done that. Other than that, all help is greatly appreciated.

Change "## Interface : 20403" to simply "## Interface : 20400".

Also at a glance, make sure you actually call Hearth in your OnClick handler. Change "Hearth" to "Hearth()". Essentially, anything in those script tags is treated just like the contents of your lua file.

Edit: Also, you need a parameter list for the Hearth function in your Lua file. Change "function Hearth" to "function Hearth ()" there too.

Thanks, I understand the bit about the TOC file, but what about my Lua/XML files? Could you please copy+paste, correct it, and post it for me?

EDIT: I tried, but it is still listed as "Incompatible". Please still correct it for me.

Oh, I just tested one of my own addons and it looks like you can't have a space in front of the colons in your TOC file. It should look like this instead:

## Interface: 20400
## Name: Looky
## Notes: An addon to use the first item in your bag (usually Hearthstone) when the button is clicked.
## Author: MelonRind
Looky.xml
Looky.lua
