Hi Tammi,
That is exactly the rubberband I used. I save those because I never know when I am going to need to use one. I slipped the rubberband around the column and positioned it over the screw head. I will also say that I had put some oil on it earlier because it wasn't budging. Then I put the screwdriver into the screwhead that had the rubberband over it and tried unscrewing it. It worked! So maybe it was the combination of oiling it AND the rubberband trick? Either way, I was a happy girl.
