Great community!
I need help to bring data from another sheet.
If data is input vertically, then I can use countifs or sumifs, etc... but it is horizontally input.
In the picture, I want to bring the number 100 (Purple) to Green square from the Sheet 2 to Sheet 1
, When customer name, product name , Year and Month is same
The Year, Month automatically change (Move to the front column) when time passed, so couldn't use the 'Cell linking' function.
Please help !!!
