Macro to hide rows based on cell

Hello!

I need to create a macro that will automatically hide a range of cells if the word "no" is displayed in a certain cell.

To give a little more information. I have a column displaying X's if an above criteria displays "no". What I need to do is hide all of the columns that have the X displayed in column A.

The column with x's named range is Crit. If you need anymore information please let me know.

Thanks!
Alex
