This occurs when you have either closed the Entry Form before the payment has gone through, your Credit Card was declined, or your browser has a particular security setting that blocks all popups.
Another common problem for those who use WIFI to connect to the internet is that insufficient Wi-Fi Network Range and Power will cause micro dropouts.
If you encounter any of these problems, simply log back into your Entry (the data is still there) and maybe change your payment selection to "Pay by Cash/Cheque" OR try other computer/connection.
NB: If you have received NO notification of your Entry (after checking your Spam/Junk Folder), then your Entry Form may NOT have been submitted. Simply email webadmin@herveybaysailingclub.org.au to confirm.
