ESOUI - Please fix this lua for me (Repair Compare)

Some weeks ago I requested at the CraftCompare AddOn to add the tooltips to the repair window.
I often just repair the gear I have equiped, I save the old parts for analysis.
Therefor I don't have to repair them. So I always have to remember what I have equiped when I repair items.

The Author Ckaotik replyed this some weeks ago but its not working for me (or I'm just to stupid to make an addon from it)?

        local icon = self:GetNamedChild('EquippedIndicator')

        if data.bagId == BAG_WORN then

                if not icon then

                        icon = wm:CreateControl(self:GetName()..'EquippedIndicator', self, CT_TEXTURE)

                        icon:SetAnchor(CENTER, self:GetNamedChild('ButtonIcon'), CENTER, 0, 0)

                        icon:SetDrawTier(DT_LOW)

                        icon:SetDimensions(50, 50)

                        icon:SetTexture('/esoui/art/actionbar/passiveabilityframe_round_over.dds')

                end

                icon:SetHidden(false)

        elseif icon then

                icon:SetHidden(true)

        end

end)

This will display a shiny blue circle behind equipped items when in a repair screen. Or so I hope it works :P

Sadly the code he posted here dosen't work for me. I just put it on the bottom of the craft compare lua and now Its not showing anything anymore (no items or names) in the repair window.

Maybe someone can upload this as an addon that works? That woud be great!
