object reference is required to access non-static member - What does this mean?

if (dev05State == true){
Sending.sendBlue (); //Surveillance Mode
SurveillanceModeManager.TogglePlay ();

I’m trying to call another script to have it activate something but I get this error message:

Assets/Scripts/CountdownTimerManager.cs(124,57): error CS0120: An object reference is required to access non-static member `SurveillanceModeManager.TogglePlay()'

You attempt to make a call to an object which has not been referenced. This only works with static members. If something is static it is Unique and can be accessed from anywhere. A non-static member requires you to tell the compiler where/what it is.

You already know this :smiley:
