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.
