Hi!<BR> I am creating a prodnum(key col) in my 1st asp file(ex:asp1.asp)(ie. 1st screen) and I want to display this prodnum value in the corresponding text box when I enter into 2nd asp file(ex:asp2.asp)(ie. 2nd screen). For this I create sessin variable in 1st asp file and I am using that session variable in my 2nd asp file. First time When I create a prodnum(ex:100) and it is displayed in the asp file(ie. 2nd screen) when I enter. But the problem is when I create 2nd prodnum(ex:101) and I enter into 2nd screen still 1st record number(ie 100) displaying. It is not displaying 101. If I give refresh(riht click on mouse) then it is refreshing the page and displaying 101.But how the user knows to give refresh each and every time? <BR><BR>So in my 2nd asp file, I gave <BR><%response.expires="-1"><BR>(according to your advice).I am getting the following error at response.expires="-1" line:<BR><BR><BR><BR>Response object error 'ASP 0156 : 80004005' <BR><BR>Header Error <BR><BR>/totalview/ProdEntryScreen.asp, line 10 <BR><BR>The HTTP headers are already written to the client browser. Any HTTP header modifications must be made before writing page content<BR><BR>Please help me how to solve this problem.<BR><BR>Thanks in advance,<BR>Anu.
