Hi Dear All,

I am looking for assistance regarding product association.
i have two sheets named (1),(summery),
if i select once item like tooth brush in sheet 1 by drop down menu then it add in sheet summery and automatically add toothpaste in its next row.
when i select next item from sheet 1 then in summery sheet it will start from blank cell.
is it possible through formulas?


Thanks in advance.
