Package variable declaration

Question

I need to declare Item_To_Go_To package level variable stored in the Instace package for the below code.
I have create a a package specification in the form as a Program Unit named "Instance".
Now i need to declare Item_To_Go_To variable which will store control name like
Instance.Item_To_Go_To := 'myblock.myitem';
I have controls like text item, list item, Checkbox. How to declare these variables?
I have used the below one:
PACKAGE Instance IS
Item_To_Go_To item;
END;
In my example Instance.Item_To_Go_To := 'User.FIRST_NAME';
is giving expression is a wrong type error. Please let me know what i have done wrong.
I have used timer expired trigger to overcome my illegal restricted procedure Go_item issue.
Code snippet.
Declare
htimer Timer;
Begin
Instance.Item_To_Go_To := 'myblock.myitem';
Create_Timer( 'wvi_nav_timer', 1, NO_REPEAT);
End;
Then in the When-Timer-Expired trigger...
Begin
If ( Get_Application_Property( Timer_Name ) = 'wvi_nav_time' ) Then
Go_Item( Instance.Item_To_Go_To );
End If;
End;
Please refer:
Alternative trigger like post_change but can 'go_item'

As you are trying to assign a varchar-value to the variable, you should declare it as varchar2 like:
PACKAGE Instance IS
  Item_To_Go_To VARCHAR2(61);
END;
