Based on your question i think you uploaded a google script (maybe review script ) , and the way you added the values blocks the current page for proceeding. Use this for delivery country :
"delivery_country": "<?php echo $googleRatingData['delivery_country'] ?>",
For the delivery date :
"estimated_delivery_date": "<?php echo $deliveryDate=Date('Y-m-d', strtotime("+12 days")); ?>",
Update the date as you want.
If this doesnt work for you , paste the full script here (without the mercant id ) so we can debug.
