paste numbers from previous column

I want to look for a fault in a formula (column C). If so then copy the number from the previous column (column B) and past as a value (in column C).
See attached file.

To change the number format it is not a problem. I just don't know how to copy the previous column from a selection I made with: Selection.SpecialCells(xlCellTypeFormulas, 16).Select

Thx in advance,
