Value of LINEST

Hi All,
I got problem when using the LINEST function (linear regression). How do one add the value of the slope to a cell?

I use the code below but I get the #VALUE! message in the cell. The cell's format is General.

   Dim v As Variant
   Dim x As Variant
   Dim Y As Variant
   x = Range("B2:B3")
   Y = Range("D2:D3")
   v = Application.LinEst(Y, x, True, True)
   Worksheets("Sheet1").Range("H1").Value = v

What is wrong here?

Cheers!
