This topic is about testing the test version of App Inventor not the regular version. What version of App Inventor are you using? The answer @TIMAI2 gave you means you have an empty socket somewhere.

I moved your posts to a new topic.

ok thank you sir

You got your answer from @TIMAI2 Did you find the blocks with empty sockets?

If not, right click on a white area of the blockeditor and save an image of your blocks and post them here.

here is the block editor code. the only place thats failed to connect the the connected text fill. can you review it

here is the exact location of it

ListPicker.Elements accepts a list, not a string. You should be setting the text of a label to "Connected."

YES Thank you boss i corrected it it works thank you sir
