搞了两天没搞定的问题：
从manage_xmzch.asp上传到search_xmzch.asp页上4个变量，分别是kaishishijian/jieshushijian/kaishichanpin/jieshuchanpin.
search_xmzch.asp接收到4个变量后，查询，并分页显示。现在的问题是，如果sql语句不带参数查询则正常分页显示，但如果带了参数，即 where 销售日期>=#"&kaishishijian&"# and 销售日期 <=#"&jieshushijian&"# and 产品编码>='"&kaishichanpin&"' and 产品编码<='"&jieshuchanpin&"' 这一句，则只能显示第一页，第二页等就显示不出来了。提示为：日期的语法错误 在查询表达式 '销售日期>=## and 销售日期 <=## and 产品编码>='' and 产品编码<=''' 中。
/sims/search_xmzch.asp, 第 57 行
可以看到这几个参数没有接收到传递的数据（第一页显示是正常的）
我把search_xmzch.asp的代码贴到这里，跪求高人指点解决：
