Cast failed - Health

Hello everyone,
From this image this all looks fine but in real… its not like that at all…

WITHOUT BINDING… Text block and progress bar are on screen while playing… (Fill percent works fine )

WITH BINDING … Text block gone progress bar is grey…
Print string on my cast failed works it prints “Hello” hehe

All this binding and scripting works fine on beginning of my game but somehow its just wont work now… I watched so many tutorials about how to set up this simple “code” but its not working Can you try help me
Thanks
