formatting function?
 

I have a spreadsheet full of validations and different
formatting. I want to protect it all but at the same
time, let the user change the values in all the cells.
Everything seems to work except with it comes down to
copy and pasting. If I copy from a certain cell with a
certain format and then paste it in a different cell with
a DIFFERENT format, it somehow overides the format.

Cell 1 has numbers
Cell 2 accepts only letters

Copy cell 1 into cell 2 and it works yet if you type it
manually without copy pasting there is a pop up with an
error.

Any ideas on how I can protect the formatting so even
the "copy & paste" won't get rid of it?!

Thanks,

Marc
