Great Grandparent Visitation in VA

My grandmother took me to court for visitation of my son. I agreed to the terms in court that should be met, every other weekend and every Wednesday is what we agreed on. My son is her great grandchild. She hasn't been complying lately to the visitation that SHE took me to court for. Can I revoke it? And Do I have a good chance of getting it revoked? I have full custody, my husband and I.
