I'm continuing to get an error (see uploaded image)

I’m continuing to get an error: "Uploading item(s) to folder ‘davidmc41@gmail.com/Contacts/’ failed due to the following error: Execution of request failed: https://www.google.com/m8/feeds/conta… ([Line 7, Column 31, element gd:email] g:email/@address is required) So what is the resolution of this problem? Please email me at davidmc41@gmail.com

Hello David, seems like some of your contacts are incorrectly formatted and include an invalid email address format, please check if you have all your contacts available on the server and try to perform a folder repair on your Contacts folder. To repair, please right click the folder and select Properties > Repair and click on the “Repair” button.

This will essentially resynchronise the folder with the server hopefully getting rid of the invalid item.
