Hi!!

I'm trying to do some simple paging with goes to the database once and then shows and hides the results to display 3 items at a time. It uses a next and previous button. The next button works but the previous button displays all previous results and not just the last three results.

What i need it to do is hide all results and show the last three
This is my code and i really do need a little help pleaaaaaase!!

<SCRIPT>
var intPosition=0;
function ShowFirstThreeItems()
{
    var i;
    i=1;
    for (i=1; i<=3; i++) 
    {
    eval('ItemRow'+i+'.style.display="block"');
    intPosition=i;
 
    }
}
function showNext()
{
 
    var i;
 
    for (i=1; i<=intPosition; i++) 
    {
    eval('ItemRow'+i+'.style.display="none"');
    }
    for (i=intPosition+1; i<=intPosition+3; i++) 
    {
    eval('ItemRow'+i+'.style.display="block"');
    }
    intPosition=i-1
 
 
}
 
 
function showPrev()
{
 
    var i;
 
 
    for (i=intPosition; i>0; i--)
    {
    eval('ItemRow'+i+'.style.display="block"');
