No problem dude.
The Code starts with <opt>
the next is ...
which ends with </PanelFile>
and inside those panels are elements which start with ...
and end with </Element>
and then you end it all with ...
(... how you started)
So, highlighted in red is what you'll need to input into your code for it to work
<Element ID="ToolbarField" X="7.5" Y="630" Width="1009" Height="138" Detach="1">
<Element ID="ToolbarFieldMain" X="0" Y="0" Width="1009" Height="138" />
Glad I could help.
Just to let you know, Turbine is doing a complete rework of the UI for Mines of Moria. So, I've paused my modding for the time being. That said, don't stop modding for yourself. You'll have your gears in motion for when the expansion is released.
Any other questions feel free to post here or send me IMs
