I am trying to create a column that list the values conditionally from multiple columns.
Data table sample

I am trying to create the new column using the condition that if Pos 1 is not empty, return that value. If it is empty, enter Pos 2. If that is empty, return Pos 3 (orange items).......The only change to this routine is that if there is an Account listed, I want Pos 3 listed as the position. (yellow items)
Desired output

Any help is appreciated, thanks
