Thx JBeaucaire. My prob is almost done but following prob still facing
1. If B28 changes with LP 407 MINIBUS, D7 doesn't become Zero and D8 doesn't become 2. But look my total qty in F7 & F8 really changes.
2. How can this formula recognize model similarity depicted in I19:I20
3. My todays report may goes down beyond B28:C48 which I collect from Branch Office and paste here
