The function you want to use is Get (AccountPrivilegeSetName). You can then either to a simple if/else if with a Go To Layout for each privilege set - should be OK for a simple case.
Thank you for the reply! I'll give that go.
That worked like a charm! Thank you Mr. Wikstrom! The coded that ended up working looks similar to this:
If [Get (AccountPrivilegeSetName) = "[Full Access]"]
Go to Layout (Admin)
Else If [Get (AccountPrivilegeSetName) = "Driver"]
Go to Layout (Driver)
Else If [Get (AccountPrivilegeSetName) = "Foreman"]
Go to Layout (Foreman)
The "Full Access" privilege set must be in brackets ( "[" and "]" ) in order for it to work, because it is a "system generated" set name. If it is a custom privilege set name, then no brackets are required. Hence, "Driver" and "Foreman."
