Mmm.first, did you create an event in the furnitures map?... (Event with ID 5).
Second, if you use my original setup, the 'wall' must be capitalized.
Now, be sure that you separate this new furniture with a collon.
Try with this:
Furnitures = {
'Picasso' => [3, 'MP_001-Barril01', "Picasso's Famous Picture",'Wall'],
'Water Can'=> [1, 'MP_001-Barril01', 'A can for water','Tables'],
'Bucket' => [2, 'MP_001-Barril01', 'A Bucket to put Plants','Floor'],
'Basket' => [4, 'MP_001-Barril01', 'A Basket to put Items', 'Table&Floor'],
'Sheild' => [5, 'MP_001-Barril01', 'A large sheild', 'Wall']
}
If you have problems yet please tell me.
