Hi Gerd/Steve, I seem to have come across an anomaly in the style compiler (or I am doing something silly). The following line does not compile: ((highway=* & motorroad=yes) | highway=motorway | highway=motorway_link) & foot!=yes & foot!=designated & foot!=permissive { add mkgmap:foot=no } But this variant compiles: (highway=motorway | highway=motorway_link | (highway=* & motorroad=yes)) & foot!=yes & foot!=designated & foot!=permissive { add mkgmap:foot=no } And so does this one: ((highway=* & motorroad=yes) | highway=motorway | highway=motorway_link) & (foot=yes | foot=designated | foot=permissive) This is the error message: Error in style: Error: (inc/access:6): Invalid rule expression: ((($highway=*&($motorroad='yes'))|(($highway='motorway')|($highway='motorway _link')))&($foot!=yes&($foot!=designated&$foot!=permissive))) Changing the != operators to = allows it to compile, so most likely a mishandling of the ! operator. Any ideas what is wrong? Mike
