[OpenLayers-Users] problem using pointRadius computed in context

[Heidt, Christopher M.]

I don't see what you had before but this wont work because
pointRadius has to be a number, not a function.
You can use a function to create the number:

//Styles
	var clusterStyle = new OpenLayers.Style({
            pointRadius: "${radius}",
            fillColor: '#ee9900',
            fillOpacity: 0.8,
            strokeColor: '#ee9900',
            strokeWidth: 1,
            strokeOpacity: 0.8,
		cursor: 'pointer'
        }, {
            context: {
                radius: function(feature) {
	
if(typeof(feature.attributes.count) != 'undefined')
					{
						return
Math.min(feature.attributes.count, 7) + 3;
					}
					return 4;
                }
            }
        });

Hi Sylvie,

I guess it was related to some errors in my javascript file. I would
suggest you to use online javascriptlint to check your syntax and
identify potential errors.
