THe screen shot is attatched.

include( "IconSupport" );
include( "UniqueBonuses" );

function ShowHideHandler( bIsHide, bIsInit )
    if( not bIsHide ) then
        Controls.MyGameScreenLogo:SetTexture( "Alex_BG.dds" );
    else
        Controls.MyGameScreenLogo:UnloadTexture();
    end
end
ContextPtr:SetShowHideHandler( ShowHideHandler );

ContextPtr:SetInputHandler( function(uiMsg, wParam, lParam)
    if uiMsg == KeyEvents.KeyDown then
        if wParam == Keys.VK_ESCAPE or wParam == Keys.VK_RETURN then
			OnBack();
        end
    end
    return true;
end);

	Controls.MainStack:CalculateSize();
	Controls.MainStack:ReprocessAnchoring();
	Controls.DoMScrollPanel:CalculateInternalSize();
end

Initialize();

this is the content of scenario starting screen. lua.log says there is a problem of loading civilization name

 -- Use the Civilization_Leaders table to cross reference from this civ to the Leaders table
	local civ = GameInfo.Civilizations["CIVILIZATION_GREECE"];
    local leader = GameInfo.Leaders[GameInfo.Civilization_Leaders( "CivilizationType = '" .. civ.Type .. "'" )().LeaderheadType];
    local leaderDescription = leader.Description;

which is this part. but CIVILIZATION_GREECE obviously exist in XML. why is it nil value?
