weird problem with session object

[keyser soze]

hi,
i have an asp page,
in which i put a "response.write " for debug

*<%= session("x") %>*
<%
session("x")= "222"
%>

now, entering the page with session("x")= "111"
the code should "response" : *111*
but it produce : *222*

seems that it send "111" to the buffer
but, later, overwrite with "222"

i can't reproduce it in other page...
but i could send the entire code
for you to read

thanks!
regards,
ks
