We have a very simple single page shopping page which connects to the SquareUP API to take payment. When the customer clicks on make payment it runs a simple process and confirms the sale.
If the customer has a slow connection and it lags which makes some people click more than once meaning the get charged more than once.
I have a couple of these pages live and on another I had a delay added so the repeat billing stopped.
I need this done on this page , i can provide the source to the other so you can see what changes were made the last time.
This is not going to take long but I need it done right now, please fully read the description, confirm you understand what needs done and be ready to start now!
