一个小问题，请高手回答?

<%

response.buffer = true

dim count

count = request.cookies("vcount")

if count > "0" then

count = count + 1

response.write("欢迎您" & count & "访问本站")

else

count = 1

response.write("欢迎您首次访问本站!")

end if

response.cookies("vcount") = count

response.flush

%>

这里的count > "0"，0为什么要加引号?不加IE会报错！
