Problem with this formula

[Samuel_Saunier]

Hi there, 

I have a single select field name "Département" and I want to concatene the 2 first letters (later for automation).

I have a problem with this formula :

IF(

  OR(

    {Département} = "75", 

    {Département} = "78", 

    {Département} = "77", 

    {Département} = "91", 

    {Département} = "92", 

    {Département} = "93", 

    {Département} = "94", 

    {Département} = "95"

  ), 

  LEFT({Département}, 2), 

  ""

)

Erreur : Missing opening parenthesis "(".

Can someone help me ?

There's nothing wrong with your formula as posted (see screencaps). I copied and pasted it, and there are no errors.
