Re: [MapServer-users] using SCALETOKEN in an EXPRESSION
Ah, good point. The examples do all show it being used in conjunction with the DATA statement.

Re: [MapServer-users] using SCALETOKEN in an EXPRESSION
According to RFC 86 SCALETOKENs are used to replace tokens inside a layer’s DATA statement - so it might simply not work within class expressions. As a workaround you might use MINSCALEDENOM and MAXSCALEDENOM within CLASS.

[MapServer-users] using SCALETOKEN in an EXPRESSION
Can anyone tell me what's wrong with my EXPRESSION below? I'm trying to filter features from the National Hydrology Dataset based on scale using SCALETOKEN and I can't seem to get it right. [Visibility] is a field in the data that suggests the scale at which a feature should be shown. Thanks!
