Hello everyone,
I try to use the Multirow formula in my process but i think i don't use it correctly, i can't find how to get the result i want..
This is the kind of data i want to process
And this is the result i want to have:

AS you can see in my workflow the field takes the previous field each time in the column ACCOUNT... i only need the Account number

Can you help me about that please ?
Thank's a lot in advance
