[Qgis-user] Tweaking an Atlas

[Nicolas Cadieux]

Hi,

This did it

IF (@atlas_featurenumber  = 1,0,1)

Intuition says this should be 1 for include and 0 to exclude but it's 
the contrary.  This is a double negative situation as "Exclude item from 
exports" must be checked as False.

Thanks for the tips!

Nicolas
