Show data based on date comparision

[fok_ste]

Hi,
I’m adding things to the database via API, while the wf will update the field “last_sync” with the current date.

Now I want to show an icon if the month of the “last_sync” value is not the current month.
i.g.
last sync: juli 2021: show icon
last sync: august 2021: dont show icon

any idea whats wrong with this setup?
