Thanks for you come here, i got the solution already.

echo "<BODY onLoad="javascript:displaymessage();">

that's not going to work. You can't have double quotes within double quotes.

and that will only work, if you don't have another body tag already there, and you want to display the message at times other than when the page loads.

I believe what you want would be:

Code:

echo "<script>displaymessage();</script>";
