Andrea,
I am not sure if anyone is interested in this but I have managed to make this work. However, I cannot get the OGC version of the filter to work at all when you multiply a denominator by a constant. See previous emails below… So I switched my efforts to using a CQL_Filter. median_tot_fam_inc_weekly > 0.0 AND median_mortgage_repay_monthly > 0.0 AND ((median_mortgage_repay_monthly / (median_tot_fam_inc_weekly * 4.3333333)) * 100) >=30 AND ((median_mortgage_repay_monthly / (median_tot_fam_inc_weekly * 4.3333333)) * 100) <= 80 This also failed when you multiply a denominator with a constant. I know this because I changed the formula to not have a multiplier on a denominator in the equation and it finally worked. median_tot_fam_inc_weekly > 0.0 AND median_mortgage_repay_monthly > 0.0 AND ((median_mortgage_repay_monthly / median_tot_fam_inc_weekly) * 23.076923) >= 30 AND ((median_mortgage_repay_monthly / median_tot_fam_inc_weekly) * 23.076923) <= 80 I may go back and try this solution with the OGC version.

I tried your isBetween option and I am still getting a geoserver rendering problems. Part of stack trace = ‘Rendering process failed java.io.IOExceptionUnable to evaulate class org.geotools.feature.type.AttributeDescriptorImpl in a numeric context Details:’ I even changed the formula around to see if the multiplication of a denominator could be the problem to yield a weekly percentage instead which also failed. <ogc:Filter> <ogc:And> <ogc:PropertyIsGreaterThan> <ogc:PropertyName>median_mortgage_repay_monthly</ogc:PropertyName> <ogc:Literal>0.0</ogc:Literal> </ogc:PropertyIsGreaterThan> <ogc:PropertyIsBetween> <ogc:Div> <ogc:Div> <ogc:PropertyName>median_mortgage_repay_monthly</ogc:PropertyName> <ogc:Literal>4.333333</ogc:Literal> </ogc:Div> <ogc:PropertyName>median_tot_prsnl_inc_weekly</ogc:PropertyName> </ogc:Div> <ogc:LowerBoundary> <ogc:Literal>0.45</ogc:Literal> </ogc:LowerBoundary> <ogc:UpperBoundary> <ogc:Literal>0.65</ogc:Literal> </ogc:UpperBoundary> </ogc:PropertyIsBetween> </ogc:And> </ogc:Filter> So given I just cannot get this to work and given that this is a simple two part filter (range) requiring only one colour classification I have decided to shift my tack on to a CQL filter. Hopefully that will work.

The style is: <?xml version="1.0" encoding="UTF-8"?> <StyledLayerDescriptor xmlns="http://www.opengis.net/sld"; xmlns:ogc="http://www.opengis.net/ogc"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="1.0.0" xsi:schemaLocation="http://www.opengis.net/sld StyledLayerDescriptor.xsd"> <NamedLayer> <Name>undefined</Name> <UserStyle> <Title>braddles tester7</Title> <FeatureTypeStyle> <Rule> <Name>Employed between 45% and 65%</Name> <ogc:Filter> <ogc:And> <ogc:PropertyIsGreaterThan> <ogc:PropertyName>PERSONS</ogc:PropertyName> <ogc:Literal>0.0</ogc:Literal> </ogc:PropertyIsGreaterThan> <ogc:PropertyIsBetween> <ogc:Div> <ogc:PropertyName>EMPLOYED</ogc:PropertyName> <ogc:PropertyName>PERSONS</ogc:PropertyName> </ogc:Div> <ogc:LowerBoundary> <ogc:Literal>0.45</ogc:Literal> </ogc:LowerBoundary> <ogc:UpperBoundary> <ogc:Literal>0.65</ogc:Literal> </ogc:UpperBoundary> </ogc:PropertyIsBetween> </ogc:And> </ogc:Filter> <PolygonSymbolizer> <Fill> <CssParameter name="fill">#FF0000</CssParameter> </Fill> <Stroke> <CssParameter name="stroke">#000000</CssParameter> </Stroke> </PolygonSymbolizer> </Rule> </FeatureTypeStyle> </UserStyle> </NamedLayer> </StyledLayerDescriptor> and the resulting map is: Appears to be working here. I cannot imagine why something similar would not work in another dataset... maybe if you can share a sample of the data, some of us here can load it up and give it a spin Cheers Andrea On Sat, Mar 28, 2020 at 2:01 PM Brad Spencer <b...@numaps.com.au <mailto:b...@numaps.com.au> > wrote: Brad, I can’t see anything wrong with the data.

This is really weird as it would appear to me that the <PropertyIsLessThanOrEqualTo> and for that matter the <PropertyIsLessThan> are not working correctly at least not on my version of Geoserver, or the Ands are not configured correctly. I get the same results testing via the geoserver app where I loaded a style with the same sld.

Do you get anything?
