Thanks, NIKK.
I can do my gutters just fine. I put my ladder in one place to get on the roof and clean all the gutters from up top. No problem.
In this case, I was putting up and down my ladder all over the house to try to seal openings under the roof that critters may use to get in. I was in a hurry because it was getting dark.
Bad mistake to be in a hurry on a ladder!
