If your post can be interpreted literally...meaning that you want a button to
hide/unhide entire columns...
Try this:

Select columns D,E, and F

From the Excel main menu:
<data<group and outline<Group

That will display a [-] button above the worksheet.
Clicking on that button hides the columns and changes the button to [+]
Click on the [+] button to redisplay the columns.

Post back with any questions.
Does that help?

I want to setup or enter a function in a cell that will allow me to use that
cell as a "button". I want to setup this cell so that when I click on it, it
will hide selected cells.

For example:

Clicking on cell "A1" allows me to hide columns D,E and F.

I'd appreciate any kind of help on this.
