请帮助我

您缺少用于运行时替换的验证块。见：

验证
“FILTRO_AREA_ATENDIMENTO”“。#这验证了所有内容
#您应该将其更改为类似的正则表达式
# '^$'
“默认过滤区域”为“某些默认文本”
结束

你是想把这篇文章发表在网站上吗？

VALIDATION
  'FILTRO_AREA_ATENDIMENTO' '.'  # this validates everything
                                 # you should change this to a regex like
                                 # '^<some pattern>$'
  'default_FILTRO_AREA_ATENDIMENTO' 'some default text'
END
