Hi

In the text box you have mention

onfocus="input_focus('tag');" onblur="input_blur('tag');"

try to remove and check

[ddymacek]

you can wrap you search code (right before $tag and after mysql_close() in an if statement like:

// this will only run the php code if the submit button was pressed on your page.
if (isset($_POST['submit'])) {
   $tag...
   // rest of your code.
    mysql_close($con);
}
