Help Consolidate method
 

Hi, Help me please
I can't make it work

Worksheets("Sheet1").Range("A1").Consolidate _
Sources:=Array("'[File1.xls]Sheet2'!R1C1:R37C6",
"'[File2.xls]Sheet3'!R1C1:R37C6"), _
Function:=xlSum

I allays get message 'Can't open file '[File1.xls]Sheet2'
Even if I write

Worksheets("Sheet1").Range("A1").Consolidate _
Sources:=aSource, _
Function:=xlSum
