Dear All,

I'd like to email my customer a Excel worksheet, however, do not want them
to change any cells (values and formats) from column A to D, only E and
onwards permitted. Also, if I have hidden some rows or column, I do not want
the person to view my hidden parts too.How can I created this effect? I
already tried Protect Worksheet and workbook, doesn't seem to be working.

Thankyou!
