Filter previously selected articles from a REF list

[JuanCruzCookdat]

Today I am faced with this challenge: I am building a form to audit different sectors within a company, the objective is that the person who loads the form, gives a score to the different areas of a business premises, the inconvenience or challenge What I find is that I cannot filter the sectors that were previously selected from the REF list, thus achieving that the person cannot load the same sector twice in the same form load, I have used this formula:

NOT(
IN(
[_THIS],
SELECT(
DETALLE AUDITORIAS[SECCION AUDITORIA],
AND(
[ID AUDITORIA] = [_THISROW].[ID AUDITORIA],
[SECCION AUDITORIA] = [_THISROW].[SECCION AUDITORIA]
)
)
)
)

Processing: screen-capture.webm…

but this only invalidates the sectors that have already been loaded, I want them to STOP appearing in that list, so the list is cleaner of excluded values
