This does not seem any error.

check your query :
just echo this statement:
$sql = "SELECT * FROM $tbl_name LIMIT $start, $limit";

see what it reflects in browser when you put $limit=3.
make sure that you are in first page ($page='').

then run that query in your database. check the result.

If result is ok there. you may have left an url variable as 'page' with some value.

remove it and check it again.

you too have an error in designing.

echo "<table cellpadding=2 cellspacing=2 width=100%> should be before while statement.

Hope you get it.

In your code $page defines the page number, $start defines the row number of starting record which will be displayed on the page, $limit defines number of records per page $page=$_GET['page']; is actualling fetching "page" veriable appended in the url. If you see the url you will see "page" appended in the url.

The problem you are facing is due to this code $start = ($page - 1) * $limit; Lets suppose if you have 6 records in the database and page you are trying to browse is 3 and limit is set to 2. In this case $start = (3-1) * 2 = 4 . In this case 5th and 6th records will be displayed.

Now suppose that you have 6 records in database and page you are browsing in 3 and limit is set to 3. in this case $start = (3-1)* 3 = 6 . By logic it should display 7th and 8th record but the database has only 6 records so nothing is displayed.
