Problem:

I have one main window in my project and an extra fram, which is called by
the main window i.e. FrameName.show()

I created a new class and initialised it in the main window, setting values
to attributes.
However, when I try to retrieve the values of the attributes in the frame
window, it tells me to initialise an instance of the class.

What i have done so far is 

Nameofclass ObjectName;

ObjectName.AttributeName = some value   //at this point the error occurs
saying that object might not be initialised,

how can i get around this?
