Hello,
Can somebody pls help me w/ this,

Above is my formula giving me the following results:
- [TranDesc] + Serial Nbr (if SerialNbr is not null)
- [SerialNbr] (if previous TranDesc is equals to TranDesc)
- [TranDesc] (if LineType is Non-Stock)
-
However, I have a problem, the highlighted part still comes out tho item has no SerialNbr. I can’t see where I’m wrong or how to add that.
Thank you in advance!
