Can someone help me with this?

Hi,

I know this is probably pretty simple, but I'm new to Roku, just need help correcting my SimpleGrid.brs file to:

1). Show an items "title" under the thumnail. Right now, its just showing the thumb, but no title. I disabled the overhang description. I just want the title to show under the thumb.

2) Also when I changed the gridstyle to : "flat-landscape" I get this huge gap at the top of the screen. I set the screen.SetFocusedListItem(1,0) and it looks fine when I load the channel, but when i scroll up, I still get the huge gap.

Any help would be very much appreciated! Thanks so much!
