Setting a variable and writing back a value with the Edited Cell action
The Edited cell action does not do the same as a writeback formula (for example, RWC or WBC). You might have an RWC formula to enter values to the database. In the same cell, you can have an Edited cell action that fills a variable. When a user edits the cell, the action is triggered and the variable is filled, but the formula is not executed.
You can change the action to allow both writeback and setting a variable.
