Returns the name of the table that contains the field that has the focus.
Returns the
table occurrence name for the active field. If there is no active field, this function returns an empty string.
There are two fields, Teachers::Name and Coaches::Name, on the current
layout based on the Classes table occurrence. The Classes table occurrence is related to the Teachers table occurrence and the CoachesA table occurrence (whose
source table is Coaches). Creating a script that returns the result of
Get(ActiveFieldTableName) to a third field will return
Teachers when the script is performed after clicking in the Teachers::Name field, or will return
CoachesA after clicking in the Coaches::Name field.
