[mapserver-users] Can Mapserver expressions contain parens?

[Lime, Steve D (MNIT)]

Steve: A width value can be a double or a reference to an attribute only (an attribute binding). It can't be an expression... You'd need to do that computation elsewhere, obviously easy with a database.

Subject: [mapserver-users] Can Mapserver expressions contain parens?

I'm trying to use a style like:

       STYLE
         COLOR "#000000"
         WIDTH (([FEATWIDTH]+.4)*10)
       END

but I'm getting:

getSymbol(): Symbol definition error. Parsing error near 
(([FEATWIDTH]+.4)*10):(line 1620)
