I have a password protected workbook. I keep getting
errors with either of the following lines.

Range("F8:F13").Font.ColorIndex = 3
Range("F8:F13").Font.Color = RGB (255,0,0)

This selection is currently white font, and upon running
the macro I would like to show it to the user (change the
font to red).

When I unprotect the workbook, the macro works fine.

TIA, Brad E.
