Hi Marcster,
First off,you don't need to use VBA for this.. You can enter the following formula for the cells you need, then use copy/paste special/values:
=TEXT(C1*100,"00000000000")
But if you really want a vba solution,
Dim TheColumn As Range
Set TheColumn = Columns("C")
TheColumn.Offset(0, 1).Insert
With Range(TheColumn.Cells(1), TheColumn.Cells(65536).End(xlUp))
.Offset(0, 1).FormulaR1C1 = "=TEXT(RC[-1]*100,""00000000000"")"
.Offset(0, 1).Copy
.PasteSpecial xlPasteValues
.Offset(0, 1).EntireColumn.Delete
End With
