Trouble 2-way- connecting calendar

Trouble 2-way- connecting calendar

Hi,

I'm having a lot of trouble connecting my calendar to my google calendar and linking 2-ways. 

Please can you help me?

I've tried using the instructions but I don't have the google options in the CRM. I'm not even sure if I'm in the place to do it, or if I should be doing it from the mail and calendar area.
