[OpenLayers-Users] Labelling depending on scale

[David Alda Fernandez de Lezea]

Hi list,
 
I'm trying to make some rules to label some features depending on the scale. My 
idea is to do something like 
 
from 1 to 15000 just the symbol
from 15000 to 50000 symbol and label
from 50000 to 1000000 just the symbol
 
So far my code looks like this:
 
var pointStyle ={
       pointRadius: pto.getGrosor(),
       fillOpacity: 1, 
       strokeOpacity: 1, 
       strokeColor: "#000000",
       strokeWidth: 1, 
       fillColor: "#" + pto.getColor(), 
       graphicName: pto.getTipo(), 
       fontColor: "#" + pto.getLabelColor(),
       fontSize: pto.getLabelSize(),
       fontWeight: "bold"
      };
      
      var pointStyleLabel ={
       pointRadius: pto.getGrosor(),
       fillOpacity: 1, 
       strokeOpacity: 1, 
       strokeColor: "#000000",
       label: pto.getLabelText(),
       labelAlign: "rt",
       strokeWidth: 1, 
       fillColor: "#" + pto.getColor(), 
       graphicName: pto.getTipo(), 
       fontColor: "#" + pto.getLabelColor(),
       fontSize: pto.getLabelSize(),
       fontWeight: "bold"
      };
 
var feat = new OpenLayers.Feature.Vector(new 
OpenLayers.Geometry.Point(coords[0],coords[1]));
           
      pila.styleMap.styles["default"].addRules(
       new OpenLayers.Rule({
        filter: new OpenLayers.Filter.Comparison({
         type: OpenLayers.Filter.Comparison.EQUAL_TO,
         property: "pila_id",
         value: pto.getID()
        }),
        symbolizer: pointStyle,
        maxScaleDenominator: 10000000,
        minScaleDenominator: 15000
       }),
       new OpenLayers.Rule({
        filter: new OpenLayers.Filter.Comparison({
         type: OpenLayers.Filter.Comparison.EQUAL_TO,
         property: "pila_id",
         value: pto.getID()
        }),
        symbolizer: pointStyleLabel,
        maxScaleDenominator: 50000,
        minScaleDenominator: 15000
       }),
       new OpenLayers.Rule({
        filter: new OpenLayers.Filter.Comparison({
         type: OpenLayers.Filter.Comparison.EQUAL_TO,
         property: "pila_id",
         value: pto.getID()
        }),
        symbolizer: pointStyle,
        maxScaleDenominator: 50000,
        minScaleDenominator: 1
       })
       
      
);
 
But I don't see the expected result. Anyone could point me out what I'm doing 
wrong??
 
Thanks in advance.
