Need Help in Module 13 Exercises

Hi,

Need some help in solving module 13 Exercises(Cricket Match Problem)

I am trying this for two days but i am not getting result, it is going into infinite loop,

i was able to print the individual runs of player, but i was not able to add them with a new variable as explained in the below written code by me called all_runs.

I tried to debug the program but the control was going to some other class, not able to figure it out, please help me

can any one help me out on this
