I'm a beginner at writing VBA macros and I need some help. What I want
to do is to provide the ability to select a range of cells in a
spreadsheet then click on a command button that runs a macro that
multiplies the content of each cell in the selected range by a
corresponding factor identified in row 2 of each column.

(Example) In row 2 the cells contain (A2)5,(B2)5 and (C2)10; Cells
A4:C5 contain values (A4)1,(B4)2,(C4)3,(A5)2,(B5)3,(C5)1. I select
range B4:C5. After running the macro the cells now contain
(A4)1,(B4)10,(C4)30,(A5)2,(B5)15,(C5)10.

If anyone could provide the code to perform this task I could use your
help. Thanks
