This code is coming from your script, it seems that it might not be crafted properly. Here is a link to the php page for the strpos function:
php.net/strpos
Here is an example of how the description is shortened within the PowerStore Admin area on the product results page:
php:
<?php echo substr(strip_tags($row_WADAProducts['ProductShortDesc']), 0 , 23); ?>
<?php if (strlen($row_WADAProducts['ProductShortDesc']) > 23) { echo "..."; } ?>
This one is limiting the description to 23 characters total, you can use some code like this and just update the recordset value and number of characters to display.
