Lighting not working on mobile preview

Hi guys,

I hope someone can help. I have been trying to export a small map to my Android device and I’ve not had much luck. I managed to get the map running on my device but for some reason none of the lights show up in the scene. This is the same for mobile preview too. I have tried changing the lights from stationary to static on someones advice but still no luck. I’ve spent the morning reading forums but seem to have hit a brick wall with my understanding of the software.

Is this a simple fix or will it be an issue with my level??

Any help will be greatly appreciated!!!
