PHP button

Hi all I have been for some time trying to get this right I need to diable a button, which I can do with javascript, all works fine until the submit \ posting part . this is my part of my code below: This is my form section: --------------------------- <form action="scanbatch.php" method="POST" name="frm" > This is my php code, if the conditions are met: ----------------------------------------------- echo "<input type=\"button\" name=\"read\" value=\"Next\" onclick=\"dob();\">"; This is my javascript: ----------------------- <script language="javascript"> <!-- function dob(){ document.frm.read.disabled=true; document.frm.submit(); } //-> </script> The button does disable the button like it should the problem is that, apart from the disabling of the button, the does not update my database. In fact it does nothing BUT if I change the "type" from "button" to "submit" in the <input> tag. Then it works I cant find away for this to work. (Co exist) Could someone please help I feel the problem defiantly lies with PHP Kind Regards and thanks in advance Brent Clark
