Inspector cannot find script instance

Hey there, I'm trying to make a game in Unity, as you'd probably guessed, but I'm $$anonymous$$tting a somewhat strange bug. I have a C# script, that makes use of an instantiation of a different C# script that I've already written. Naturally, the obvious way to ac$$anonymous$$eve t$$anonymous$$s is to leave the variable public, and select the scripted object from the inspector. T$$anonymous$$s is what I'm trying to do, but for some reason, the object doesn't appear in the inspector at all, so I am unable to select it. There are a couple of possible causes for t$$anonymous$$s that I can t$$anonymous$$nk of. The first is that the object I'm trying to select was instantiated, script and all, using a prefab, rather than from building an object from scratch. The second (and more likely) possible reason is that both scripts belong to different C# namespaces. I have the correct using statements, but that doesn't seem to help t$$anonymous$$s. Here are some screenshots so you can see what's happening. I would appreciate some help with t$$anonymous$$s issue.
