Logical expression error

[jeeyoung.lee@…]

Logical expression below is not working...
If I'm correct, expression below should return all cities, but Mapserver 
doesn't return anything

EXPRESSION (('[CITY_NAME]'='Bigfork' AND [ACRES]=1021.693) OR  
('[CITY_NAME]'='Effie' AND [ACRES]Eq3577.986) OR '[CITY_NAME]'='Warba' 
OR '[CITY_NAME]'='Bovey') COLOR 225 225 90 TEMPLATE "mcd90py2.html" END

I think I've nailed this one. Not a trivial fix. The error was not related to
the parser/lexer but in how expressions were parsed for item substitution
strings. Duplicate items were not handled properly in some instances. The test
expression provided now works anyway.
