[SOLVED] How to make code wait until :MoveTo() is finished?

So I am trying to make a code that makes a dummy walk to random positions across the map. I am using a system that involves using a while true do statement. the thing is, while the dummy is walking, another :MoveTo() code interferes. if have tried to use repeat wait() until humanoid.MovedToFinished ('humanoid' is a variable for the dummy's humanoid, if you couldn't guess). Anyhow, that didn't work apparently. I'm stumped. I need the gods of scripting to shine upon me. Help?
