I want to set a page number of a page

The problem is when I try and use $page further down in the body $page is
0
Question <?=$page; ?> <BR />
<? echo "page is".$page; ?>
<?=$question[($page-1)]; ?>
I also get an undefined index notice
Notice: Undefined index: page in
c:\Inetpub\wwwroot\lss\module_one\evaluation.php on line 8
page is 1
but I though if I do a if(!isset($_REQUEST['page'])) this is the way to
set
a previously undefined index?

Firstly, there is no need to set the page by adding 1 to $_REQUEST['page']
if $_REQUEST['page'] is not set, why not do this:
$page = isset($_REQUEST['page']) ? $_REQUEST['page'] : 1;
