Our EDT2 program is designed to send ALL ITEM DATA, so everything from all your tabs will be included with your uploads.
We strongly recommend you spend time properly filling out the Details field on the General tab for your items, as notated in the Field Definition chart that your Web Description will include information from this tab.
In addition, we encourage you to also use your Stones tab to hold your stone information. Taking the time to properly fill out these fields will greatly benefit you once your web developer takes over organizing your inventory and making it searchable at a granular level.
