Formula excel with several conditions

[Aretradeser]

On a sheet1 I have some supporting data, in A1, A2 and A3 the titles; and in B1, B2 and B3, the quantities. On sheet2 some operations with formulas.


I want to achieve the following:


In A1 (sheet2), using a formula that includes the title that is in A1 (sheet1), but with the following conditions:


If the value of B1 (sheet1) is greater than zero, let me record the title that is in A1 (sheet1) in cell A1 (sheet2).


If the value of B1 (sheet1) is zero or blank, leave cell A1 (sheet2) blank.


And so, with B2 and B3 (sheet1), in A2 and A3 (sheet2)


This I think I have achieved through the formulas:


Cell A1: SI(Y(Sheet1!B1="");"";Sheet1!A1)
Cell B1: SI(Y(Sheet1!B2="");"";Sheet1!A2)
Cell C1: SI(Y(Sheet1!B3="");"";Sheet1!A3)


On the other hand, I require;


What if, in cell A1 (sheet2), you find the record of cell A1 (sheet1), I enter the value of cell B1 (sheet1), in A2 (sheet2).


But if A1 (sheet2) is blank, cell A2 (sheet2) also remains blank, not with the value zero.


And so with the other two pairs of cells: B1, B2 and C1, C2.


If needed, I can send a test file, for your better understanding.
