The usual way to reference a sheet is here but how do you reference a sheet when the sheet's name is a value in a cell?For example, A1 = Sheet number twoB1 = A1&!B4Here I want B1 to display the value in 'Sheet number two'!B4 but it's not working for me.  Any ideas?
Refer to Sheet with value in Cell?
google spreadsheets
You need to use the indirect() formula. So in cell B1 you need to put this formula:=indirect(A1&!B4)
