Hi @Marika_Vallier
Let's try the formula "OR("A", "B", "C")". The result should be 1.
With your formula, "Blabla" would only be obtained if "Entry=1".
It can be written in various ways, but if the SWITCH function is used, it will look like this.
IF(
SWITCH(ENTRY,
"A",1,
"B",1,
"C",1,
0
),
"Blabla",
"hal"
)
