When a product variant is chosen, or in our case a license type, allow a verification message to appear to make sure that is what the user really intends to purchase. For example, if I choose “1 User License” a popup should occur that states “The 1 User License is only for one user on one PC, other users will not be able to use the product. Are you sure? Y/N ” or in the case of clothes, if I choose size “Medium” a popup should occur that states “Size medium fits waist sizes 32-34 only. Are you sure? Y/N ”
You may see our license type drop down here that currently only asks questions when the Single User License is chosen: https://www.idautomation.com/IDAutomation-Code-128-Font-Advantage-Package-P43.aspx
