Index exceeds the number of array of elements error

When I try to enter values the error " Index the number of array elements" appears. I do not know what is wrong please help

clear;
clc;
max = input('Enter limit for vector: ');
askingPrice = input('Enter the asking price: ');
n = 1;
count1 = 0; %starts count for how many are in each category
count2 = 0;
count3 = 0;
count4 = 0;
count5 = 0;
totalSum = 0;
while (n <= max)
    x(2,n) = input('Enter diameters:');
    n = n + 1;     
end
 if (x(1,n) < 8)
        count1 = count1 + 1;
        totalSum = totalSum + 150;    
    elseif (x(n) >= 8 && x(n) <= 10)
        count2 = count2 + 1;
        totalSum = totalSum + 200;
    elseif (x(n)> 10 && x(n) <= 12)
        count3 = count3 + 1;
        totalSum = totalSum + 500;
    elseif (x(n) > 12 && x(n) >= 15)
        count4 = count4 + 1;
        totalSum = totalSum + 700;
    elseif (x(n) > 15)
        count5 = count5 + 1;
        totalSum = totalSum + 1000;
    end
profit = totalSum - askingPrice;
disp(['Profit is #',profit]);
disp(['Jumbo amount: ', count5]);
disp(['Extra Large amount: ', count4]);
disp(['Large amount: ', count3]);
disp(['Medium amount: ', count2]);
disp(['Small amount: ', count1]);

n = 1;
count1 = 0; %starts count for how many are in each category
count2 = 0;
