Password protecting & hiding columns

Excel question
Hey guys, i'm currently working on a log in excel for 3 people. In this log it will indicate when they begin and finish work on projects also there wil be a column for comments. There are 3 columns for comments, 1 for each user, and these comments are mostly constructive critism to help them in future projects.

Now all of this log is in 1 worksheet and I would like to hide each comment column so that other users can not view others comments. Is it possible to password protect and hide each of the 3 column with a separate password so that only the intended viewer will have acesss to the comments?

I would like the password to disable the hide feature for the column so that they can view the comments. Also I would like the hidden column to be protected from editing from everyone except me.

Is this doable with excels built-in password protect feature? Or do I have to go the macro route? If I do have to write a macro can anyone point me to some references on how this can be done.

Thanks guys!

The macro route is how you'll have to go, but Excel worksheet security .... is easily bypassed if you know how/want to.

I'm not sure how easy it is to bypass the workbook security -- never had need to know.

Someone else may be able to give you more constructive feedback.
