How do I fix this error? I have more errors but this is the main one

Assets/Bounce2.cs(32,111): error CS1061: Type UnityEngine.Transform' does not contain a definition for postion’ and no extension method postion' of type UnityEngine.Transform’ could be found (are you missing a using directive or an assembly reference?)

“position”, not “postion”. You should probably use autocomplete to check those kinds of compiler errors.
