changing screen using block editor.

I am having problem in changing screen in "app inventor 2"

i have created 2 screens as "screen 1" & "screen 2".
then i am adding a button in "screen 1"
then going to block editor .... and clicking the desired blocked.....i hv attached a picture with it .... please see and post the required changes 

A Text block as the text:

As Enis said above:

Be careful ... what you type has to be the exact screen name.   Screen 2 is not Screen2 is not screen 2 is not screen2.  AI2 and Android treats each of these separately.

Merry Christmas,
