出现这样的错误
"错误类型：
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC SQL Server Driver][SQL Server]第 1 行: ',' 附近有语法错误。
/oasystem/addnotice.asp, 第 73 行"

部分代码是:
<%
if request.form("submit")="确定" then
session("title")=request.form("title")
session("content")=request.form("content")
sql = "Insert Into notice_inf (username,notice_title,notice_content) Values( " & username & "," & session("title") & "," & session("content") & ")"

conn.Execute sql,0,1
'把是否看过通告改为"no"
sql = "update userinf set seenotice='0'"
conn.Execute sql,0,1
%>

应该怎么解决啊

sql = "Insert Into notice_inf (username,notice_title,notice_content) Values(' " & username & "','" & session("title") & "','" & session("content") & "')"

你表中的username,notice_title,notice_content这3个字段都应该是字符串类型的吧
把VALUE后边的变量加上单引号

谢谢啦!
