I run this bit of code to find the address of the the last cell in column K.

Sub test()
Dim x As Range
Worksheets("NCSA_ISS_ITEM_BOM").Activate
Set x = Cells(Rows.Count, "K").End(xlDown)
MsgBox x.Address
End Sub

I would like to save the resulting row address as a variable to run as part
of another set of code.

How would I go about doing this?
