Insert black between concatenated values

[Elodie_Delneuf]

Hello :wave:t3:

I get concatenated values from a roll-up.
The result is: CotisationsONIRCP
I want this: Cotisations ONI RCP (with black in between each value)

I tried using this formula but it does not change anything:
CONCATENATE(values)&SUBSTITUTE(“”," ")

Any advice?
Thanks!

Hi Elodie, try using ARRAYJOIN(values, " ") instead
