I need a sell adress as return value of the function(or some way for it to appear in a current cell ). How can i do that?
Does this work for you? Place it in cell A1.
=ADDRESS(ROW(A1),COLUMN(A1),4)
There is a function returning the address of the cell: =CELL("ADDRESS")
Please take a look in the help to see what other information this function can give.
