I made a cartodb map with 2 layers. The layers draw from the same table but I use filters to display some of the data in one layer and some of the data in another. Without the layers my info windows were working and now they're not. I'm not sure how to start troubleshooting this.
The SQL expression on layer 1 is
SELECT * FROM table_name WHERE useful_column > 0 and on layer 2 it is
SELECT * FROM table_name WHERE useful_column IS NULL -- the goal is to use a different info window altogether on the regions where
useful_column has no data.
