[OpenLayers-Users] Styling point features by attribute values

[Vishal Mehta]

I'm trying to get point features ( in a vector kml layer) size to scale with
an attribute value named "Water_Leve"

I tried to test this in Firebug like this:
map.layers[1].styleMap.styles.default.defaultStyle.pointRadius='${Water_Leve}';

and got the error message:
Unexpected value ${Water_Leve} parsing r attribute.

I think that the attribute may have been registered as a string when i
created the kml file from a shapefile earlier (is there a quick way to check
the data type of an attribute in firebug?)

So i tried to convert it to float on the fly like this:

map.layers[1].styleMap.styles.default.defaultStyle.pointRadius=parseFloat('${Water_Leve}');
and got the message:
Unexpected value NaN parsing r attribute.

Can someone help me get this right?

Thanks,
Vishal
