Converting a for loop to a while loop

I'm trying to convert this for loop into a while loop but keep getting the x value of the while loop as zero when it should be random values.

    % code
x=0; 
y=randi(100,1,5); 
for i = 1:5     
    x=x+y(i); 
end 

This is what I have:

    % code
 x=0;
 y=randi(100,1,5);
 while i<6 && i>0
     x=x+y(i);
    i=i+1;
 end

Not sure how to get the x value to 'work'
