[pmapper-users] FILTER on a SHAPEFILE

[John B. <be...@kn...>]

Dear List,

I am trying to use FILTER in my mapfile.  I am using this expression

FILTER ([PolyType] = 'SQUARE’ and [PolyID] = 9)

I have two fields in my shapfile (PolyType and PolyID) and I have a record with PolyType = SQUARE and PolyID = 9
The PolyType field is a string and the PolyID field is an integer.

When I use this expression

FILTER ([PolyID] = 9)

It works fine, but if I try and filter on the PolyType field (a string) it bombs.  

I have tried every combination for the String ‘SQUARE’ with and without quotes
but I cannot get it to work.  Any ideas?
