HELP!!! Excel Protection ?

[obermiller24]

OK, i am tring to put an Excel Document on a Shared Site. I want to make the document able to have the capability for others to write into the document then save and close and if they come back into the document i do not want them to be able to change what they wrote in the cells or the colum. But I still need to be able to change everything.

Is this possible?

I tried that but I need the protection to be even more specific to the cells and colums. We tried those steps but with no success.
