Good afternoon,

I am struggling with the labels and I would like to have some expression for setting the visibility of some layers based by scale.

How can I make some of them disappeared?

I tried:

   if(@map_scale<2000) then ("fid" = 18) = NULL

where "fid" is my data attribute table column NULL - label invisible when scaling smaller than 2000.

It doesn't work

UPDATE:

According to the answer below, I used the following expression:

  @map_scale<2000 AND FID = 12

and I see, that the label I wanted to disappear is displayed, whereas all others I want to keep are gone.

How can I turn it around?
