A bit ugly though, but that should fix both:

function goThere() {
echo $1
    if [ -d "$1" ] ; then
            cd "$1"
            return $?
        fi
    return 1
}

function countArgs() {
        return $#
}

function j() {
choices=$(query "name=\"$1\"" | tr '\n' ' ')
eval "countArgs $choices"
case $? in
    0) return 1;;
    1) eval "goThere $choices" ; return $?;;
    *)   PS3='Choice: '
         eval "\
         select curChoice in ${choices};\
         do\
            goThere \"\$curChoice\";\
            if [ \$? -eq 0 ];\
            then\
                break;\
            fi;\
        done"
esac
}
