Sync outlook, samsung and google calendars

[AndrewMiller]

Hi.
I want to sync my phone, googleweb and outlook.
Under "calendars to sync" I have the option to include "me"@googlemail.com.
Under "Advanced" I have the option to include folder "me"@googlemail.com/calendar(This computer only).
What is the difference or effect of selecting one or the other, please?
Thank you very much.
