Hi, I would like to label Polygons of a shape. The names for the polygons are in my table-column N5.
so I took the code from the geography-class example and tried to use that but it doesn't work:

/* LABELS!!  Fonts and font sets can be assigned to variables. The first font
   will be preferred, and fall back to subsequent fonts for characters
   that are not available, or if the entire font is not available to
   Mapnik. */
@futura_med: "Futura Medium","Function Pro Medium","Ubuntu Regular","Trebuchet MS Regular","DejaVu Sans Book";
@futura_italic: "Futura Medium Italic","Function Pro Medium Italic","Ubuntu Italic","Trebuchet MS Italic","DejaVu Sans Oblique";
@futura_bold: "Futura Bold","Function Pro Bold","Ubuntu Bold","Trebuchet MS Bold","DejaVu Sans Bold";

/* ---- Bundeslaender Schrift ---- */
#Bundeslaender[zoom>1][TYPE='Sovereign country'],
#Bundeslaender[zoom>1][TYPE='Country']{
  text-face-name: @futura_med;
  text-fill:@line * 0.6;
  text-size:9;
  text-transform:uppercase;
  text-halo-fill:rgba(255,255,255,0.5);
  text-halo-radius:1;
  text-line-spacing:1;
  text-wrap-width:20;
  text-name:"''"; /* hackish? */

  [zoom=3] { 
    text-size:10; 
  }
  [zoom=4] { 
    text-size:11; 
  }
  [zoom=5] { 
    text-size:12;
    text-character-spacing:1;
    text-line-spacing:1;
  }
  [zoom>5] {
    text-size:14;
    text-character-spacing:2;
    text-line-spacing:2;
  }

  [zoom>=2][zoom<4] { text-name: "[N4]"; }
  [zoom>=4] { text-name: "[N5]"; }

}

#Bundeslaender[zoom>4][TYPE='Dependency']{
  text-face-name: @futura_italic;
  text-fill:@line * 0.6;
  text-size:9;
  text-halo-fill:rgba(255,255,255,0.5);
  text-halo-radius:1;
  text-line-spacing:1;
  text-wrap-width:20;
  text-name:"[N5]";
  [zoom=6] { text-size:10; }
  [zoom>6] { text-size:11; }
}

What I didn't get is where I should link to the N5 column. The code I put into the style.mss

could anybody here help me with this problem?
best regards desputin

ps This code-block editing is a big mystery to me. What am I doing wrong?

   Hey Chris,

   As far as the code blocks, backticks only work on inline code, unfortunately. You can indent long stretches of code by indenting a line or all lines 4 spaces.

   So, in the datasource inspector in TileMill, you can see the column N5 and it's specifically N5? The column selection is case-sensitive. Are you running TileMill from the OSX executable?

   If you're running the OSX executable, can you open Window -> Console from the .app and see if there are any error messages while you're viewing the style? If Mapnik can't find the column, it'll log a list of columns that it can find and that you can display.

   Hi Tom,

   thanks for the answer.

   No, I'm running ubuntu. Where can I find the error console there?
   I'm familiar with case sensitivity of unix based systems and it really is N5 which is right there in bold letters.
   (It also could be that there is something wrong with the shape-file or the dbf because the color assignment for one of the polygons within this layer is not working even though it is definitely assigned correctly...)

   If you're running Ubuntu, any errors that TileMill gets internally should be in the terminal in which you started ./tilemill. Is there anything there?
