Error 1013 Issue!

Hi there, I had this class working fine but i’ve just added some more functions and now im getting thrown this error:

1013: The private attribute may be used only on class property definitions.

I really don’t understand what this error means as all my private functions have been working fine.

I’ve searched the internet and forums and couldnt find any relevant, any help would be brilliant.
