}my code doesn't work.
it says that it reached the end of the file while parsing.
if anyone can help that would be helpful.
Cheers,

Go through your code and make sure your brackets are paired up properly. Use Ctrl-Shift-I to auto-layout so you can see at what level of depth each line is at. Turn unwanted double pairs into single pairs. The parsing error should no longer appear once the brackets, "{' and '}', are paired up correctly.
thanks
still doesn't work and i don't know why.
I have showed my teacher and he said it should work.
The curly brackets match up in every file.

}I am not sure about the logic between lines 56 and 60. Looks like an unwanted semi-colon as well as double coding. But, also, got to make sure the while condition will change (become false somewhere within the loop. I cannot be sure it will just by turning.
Thanks it works now.
However when i opened it again the last public the P was for some reason wrong.
ill just fiddle with it for a few hours.
Thanks for the help danpost.
Have a great day,
