This isn't actually a problem but it does appear to be an inconvenience.
Customers do not need to log on to purchase from my clients website. When they want to make a purchase they need to fill in required fields but when they don't so this and hit the purchase button they stay on the checkout page and red text appears showing the information they have omitted. The issue that arises appears to be that when they add the missing information the rest of the information appears to be in the other fields but is not stored so when they purchase button is clicked on for a second time, all of the "required" fields say they need to be filled in again. This is a bit messy and has caused a number of customers to claim their post code or zip code is not being accepted.
The solution is:
1. For every customer to be very accurate and not make a mistake when filling in the checkout details for the first time.
2. For the software to store the information that was filled in correctly and then add the missing information when it is added by the red text prompt.
Please can somebody let me know if there is a solution to this.
