Hi Bre,
In Groups you are indicating which group a user belongs to, is Users another related table that you are bringing in or is each record on the groups table a user and a multi-select field of the groups they belong to or some other way of indicating which group they are in?
Is there a direct relationship between Groups and Documents or is that multi-select field just created by selecting Input type is "from another field" under the field settings? Because a multi select field can't be used as a reference field for a relationship and not having a relationship between those two tables can change the way you would try to solve this issue.
