New height/width coverart properties and VB

I try to create new custom column to display coverart's height/width in VB.
But I don't understand why this failed...

' Implement the CoverArt column
Function OnPochette(scriptColData)
	If scriptColData.item.metadata = "audio" and scriptColData.Item.Metadata.Audio.Coverart > 0 Then
		scriptColData.value = scriptColData.Item.AudioMeta.CoverArt.width & "x" & scriptColData.Item.AudioMeta.CoverArt.height
	End If
End Function

Please give the full script & details of what's failing and how, so we know what to look for.

(Is it generating an error in the script log? Or outputting the wrong value, or blank values? Or something else?)

Comparing Custom Column: CoverArt dimensions (or the updated scripting docs) to your code, you are using:

Item.AudioMeta.coverart

But it should be:

Item.Metadata.audio.coverart

That error should have been reported in the script log. Remember to look in the script log if things don't work. It'll often give you useful information.

Sorry, I was a little fast.

option explicit

Function OnInit(initData)
	initData.name = "ColonnePochette"
	initData.desc = "Ajoute une colonne avec la taille des pochettes."
	initData.copyright = "2014 Albator V (Michiels Thomas)"
	initData.min_version = "11.5.5"	
	initData.version = "v1.0"


	Dim col

	Set col = initData.AddColumn
	col.name = "Pochette"
	col.method = "OnPochette"
	col.label = "Pochette"
	col.header = "Pochette"
	col.justify = "right"
	col.autogroup = false
	col.autorefresh = true

End Function

' Implement the CoverArt column
Function OnPochette(scriptColData)
	If scriptColData.item.metadata = "audio" and scriptColData.Item.Metadata.Audio.Coverart > 0 Then
		scriptColData.value = scriptColData.Item.AudioMeta.CoverArt.width & "x" & scriptColData.Item.AudioMeta.CoverArt.height
	End If
End Function

Nothing is display to this column because log said...

ColonnePochette: Erreur à la ligne 28, position 3
ColonnePochette: Cet objet ne gère pas cette propriété ou cette méthode: 'scriptColData.item.AudioMeta' (0x800a01b6)

@AlbatorV, you're still a little too fast. You still have "scriptColData.item.AudioMeta" items to change to the correct one.
This line seems to be work:

scriptColData.value = scriptColData.Item.Metadata.Audio.Coverart(0).width & "x" & scriptColData.Item.Metadata.Audio.Coverart(0).height

.coverart is a collection.
When you want the properties of the coverarts you have to use .CoverArt(number).propertyname, or enumerate .CoverArt.
Each item is a AudioCoverArt object.

Many thanks @myarmor
