Creating a Command Button/Macro to hide and display rows in a Column based on value

I am trying to write what should be 2 simple Macros.

In column A there would be Command Button 1 and Command Button 2.

When you select Button 1 a macro would be run that hides any row that does not have a value in Column D.

When you select Button 2 those rows that are hidden would be unhidden.

A sample file is attached.
