[JS] Object reference not set to an instance of an object

Hello Community,

i have a little problem with my JS code.


var txtRadio : GUIText;

In the Update function:
txtRadio.text = (RadioName + ": " + CurrMusic.name);


This is just the little part of the whole Script, but i think it is enaught.
So what it does: It displays the name of the Radioname and the current Musikname on a GUIText.

This is the Error i get:
NullReferenceException: Object reference not set to an instance of an object
Radio.Update () (at Assets/Scripts/Radio.js:86)


Thanks if somone can help me, i tried some stuff out but the Error is still there.

 

That error means the component you are trying to access is invalid.

Can you show your entire script? How are you accessing currMusic?

 

Hey,

this is the entire script:

The joke is, that the script is working perfect, the line where the Error is, is working perfect, but I can´t see that Error coming up on every start anymore.
