# runoff tabulate error :( tabulate counts votes when multiple candidates are eliminated

Hello, I've been getting this error on my code. :( tabulate counts votes when multiple candidates are eliminated tabulate function did not produce correct vote totals

I've run debug 50 on it on a situation where there were two eliminations (4 candidates, 6 voters), and it seemed to work okay. Am I misinterpreting the mistake?

Actually your approach is very good to `tabulate` the vote count But,

Have you noticed, that you only should have to update the vote count for the candidates that has been preferred first rank, and how you can access the first preference?

Remember,

`preferences[i][j]` is basically `preferences[row][coloumn]`

So, To count only first ranked candidates you should do,

`preferences[changing_row];`

Assign it to an `int` and then update the vote count of that candidate if candidate is not eliminated.

if candidate is eliminated, then be sure to move to the next highest rank i.e.

``````preferences[changing_row][next coloumn];
``````

If you need any further assist, get back to me I will help you :)

To keep others answered too, be sure to tick the answer if I helped you :D

• Thank you! I think I understand what you did, and I see that your program works, but I'm still a little lost. What happens if preferences[i] is also eliminated? – mushie2 Jul 12 at 14:46
• Oops..I think that's the corner case.You should be able to think about it but one thing don't get stuck there, use check50 to ensure the correctness of the code. – Shahroz Ali Jul 12 at 16:18
• Yeah, I was pretty stuck on that. I understand now, thank you! – mushie2 Jul 12 at 21:56
