Can you be a little more specific?
What is the variable "Product", an array like
$product = array('Banana', 'Apple', 'Orange');
?
Or is Product the result of your database query? 'cause then it is a "resource", which is actually a table of the data you queried. If that is so, the easiest way to get get the number of rows from your result query is to do
$Total = mysql_num_rows($result);
And remember, the count function will return the number of elements in an array...
