Extended info – Mostloved tracks

Sorry for all the topics, I’m an a intensive user of the skinning thread Tongue
I’m trying to do a horizontal automatic scroll list with the most loved tracks of an artist.
I made something like this. The problem is that nothing appears and I have errors on the log file

PHP Code:
<control type="list">
                <
itemlayout height="64" width="300">
                    <
control type="label">
                        <
scroll>true</scroll>
                        <
width>300</width>
                        <
scroll>true</scroll>
                        <
centertop>50%</centertop>
                        <
height>64</height>
                        <
align>left</align>
                        <
aligny>center</aligny>
                        <
font>Flag</font>
                        <
textcolor>Dark2</textcolor>
                        <
label>$INFO[ListItem.label]</label> (tried title too)
                    </
control>
                </
itemlayout>
                
                <
focusedlayout>
                    <
control type="label">
                        <
scroll>true</scroll>
                        <
width>300</width>
                        <
scroll>true</scroll>
                        <
centertop>50%</centertop>
                        <
height>64</height>
                        <
align>left</align>
                        <
aligny>center</aligny>
                        <
font>Flag</font>
                        <
textcolor>Dark2</textcolor>
                        <
label>$INFO[ListItem.label]</label>(tried title too)
                    </
control>
                </
focusedlayout>
                 <

I’m sure that I’m making something wrong because I’m new at this list and content stuff, but I don’t know what. That’s why I need your help.

Thanks in advance
Best Regards
