I was able to get it working by moving the script tags as you mentioned. They were way off.
Two other items. I am not able to get the the business_address field to show up in the info window even though I have a custom window as follows (and business_name is in the record set):
<?php echo $row_Google_Recordset['business_name']; ?>
<?php echo $row_Google_recordset['business_address']; ?>
<?php echo $row_Google_recordset['city']; ?>,
<?php echo $row_Google_recordset['state']; ?>
<?php echo $row_Google_recordset['zip']; ?>
The business_name never shows up in the window.
