I need help creating a macro that will hide and unhide rows when the macro button is clicked. I need to hide rows 11 through 28 if column "I" is blank. I would like to add the macro button to be able to hide the rows that do not have a value in column "I" but if rows need to be adjusted click the macro button to show all rows. If it is possible to make the macro to work for all sheets between the tabs labeled First and Last that would be a great bonus. Any help would be greatly appreciated.
