Active window goes blank..

Hi!

I have search engine created with php and mysql.
It displays items based on keywords entered by the user

Now, i have a small javascript to display this message:

'The item has been added to your shopping cart!'

using a alert() window

Now when this is displayed, the output screen goes blank

Should i use PHP_SELF?

Ok,

This piece of code writes an item to a database table and then displays the window:

<?php
session_start();
$dis=session_id();

mysql_connect ("xxxxxxxxxx", "xxxxxx", "xxxxxx");

$dbcnx2 = @mysql_connect ("xxxxxxxxxx", "xxxxxx", "xxxxxx");

mysql_select_db ("cart", $dbcnx2);

////////////// Write variables to the database ///////////////

$write_statement = "INSERT INTO cartdata (cid, cdesc, csize, cres, cprice, cust) VALUES
($cartidnum, '$cartdesc', '$size_var', '$res_var', '$price_var', '$dis')";

mysql_query($write_statement) or die(mysql_error());

?>
<script language="JavaScript">
alert("The item has been added to your shopping-cart!");
</script>

When this script is called upon when clicking the 'add to cart' link in the output window where all the items are displayed, the screen goes blank..

Any idea?

the alert should be placed before the </body> tag - and no higher up the page as it will stop the page from loading.

Therefore if your alert is in the head section (where you'd think it should be) the whole page will seem to stall.

Also if you are chasing page speed consider

where the function scalert knows that 100 means "The item has been added to your shopping-cart!"

Not so important here but some of the strings may be more complex.
