what are blocks after that? are you switching or closing screen on any blocks?

and if you are just using set project bucket then how it will get info data?

U not declared send value in screen 1 blocks so how can you get data in screen2 (info screen) initialize.

Set startvalure in screen1 your problem is solved.
