Running the text file doesn't work anymore

I can't seem to run the file anymore....
can anyone tell me what's wrong?
I select all the code then use Ctrl + Enter , but nothing happens

Thank you

Hi, Thank you for helping.
I pasted the entire file before and it ran the program completely
the second time it didn't work anymore.

alt + enter worked
Thank you,

yeah its okay any way any type of code u want to run just fallow step by step, i mean run all libraries first then only fallow one bye one

ok, thank you :slight_smile:
