Saying Thanks by clicking the Scales

How do you give someone some "Thanks" that helped you solve a problem, even though they did not directly reply in your thread?

I was able to solve a problem of mine by using some code that Domski wrote and posted on another forum. I placed a link to that post in my thread where I was having trouble, but I didn't get to add to his rep.

I was trying to use a poorly written attempt of my own and had really become frustrated that I couldn't get it to work and his code worked perfectly.
