Session variables not making sense to me

[Streets 77]

I have been trying to create a simple little if statement where if a certain
var is incremented by clicking on a link, then a new date is shown. It works
in a fashion but then stops after the else statements go further than 4. Not
sure what's happening here, but I'm sure someone out there will be able to give
my head a shake for me.

2 pages. Both asp. Display page and update page. So if you click on a link
on the display page, you get transferred to the update page, which changes the
sesh var, then immed redirect back to the display page. The date being shown
is in a var called "dateX". Here's the code on the display page that works,
but only for the first 4 statements. Once you get to the 5th, it just holds
the last state of "dateX". Any thoughts?

<%
if (Session.Contents("varQuart1")==0){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth"),1)}
if (Session.Contents("varQuart1")==1){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+3,1)}
if (Session.Contents("varQuart1")==2){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+6,1)}
if (Session.Contents("varQuart1")==3){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+9,1)}
if (Session.Contents("varQuart1")==4){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth"),1)}
if (Session.Contents("varQuart1")==5){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+3,1)}
if (Session.Contents("varQuart1")==6){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+6,1)}
if (Session.Contents("varQuart1")==7){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+9,1)}
if (Session.Contents("varQuart1")==8){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth"),1)}
if (Session.Contents("varQuart1")==9){Session("dateX" )=new
Date(Session.Contents("dateXYear"),Session.Content s("dateXMonth")+3,1)}
%>

Figured it out - was the order in which i had my statement on the page. The
initial "dateX" state wasn't in front, so it wasn't initialising properly. But
weird that it managed the first few if statements before failing.

Cheerios.

I don't know asp nor how arrays are indexed there but did it start at offset=1 instead of 0? Session variables in php (or for a better term, arrays) start at 0.
