Can u change rating to SOLVED my problem after made mistake and gave member credit only for HELPING with problem's solution

I asked how to transfer my iPhone's NOTES to the NOTES application

on my Mac Book Pro. A member SOLVED the problem. But I made a mistake &

only gave him/her credit for HELPING with the solution.

How can I go back and edit and change my rating to give him credit for

SOLVING the problem. My original question was my first use of this support

community.
