I have been having problems protecting my worksheets, using the normal manner, mainly it does not seem to work, So i came up with another idea, but cant seem to work out how to do it.

I have a workbook with about 7 worksheets, this needs to be sent via email to our customers, and on two of the worksheets the customer can enter there comments and then email back the workbook, the problem is that i cant protect the data.

So i was thinking is it possible to use VBA to program a function i can enter in to the toolbar that the user can lock all the cells in the whole workbox except for two columns when they finish entering in data, maybe with a password for locking it and unlocking for the original user so that they can unlock the cells for editing.
