Well, what errors did you get? Or did you not get any errors? Have you tried putting curly braces around whatever’s supposed to be inside the if statements?

They wouldn’t get any errors with the @ in front of everything as that will suppress errors.

[php]

<?php $sql = "select * from details"; $query = @mysql_query($sql); $countData = @mysql_num_rows($query); ?>

// @ is suppressing any errors the script is going to pass.
[/php]

Should be -

[php]

<?php $sql = "select *from details"; $query = mysql_query($sql); $countData = mysql_num_rows($query); ?>

[/php]

Unsupress everything run and see what errors you are getting. Then if you still can’t figure it out, come back to us with the error and we can try and help.
