Storing values in a vector using a loop

This is a simple version of what i'm trying to implement in a function:
d = zeros(1,N)
for i = 1:N
d(1,i)=input('Distance = ');
end
I thought I was storing the ith value in the vector, but when it saved to my workspace it came out as a scalar!?
How do I create a vector of values using a loop? Why is it not working?

N = 3;
d = zeros(1,N)
for i = 1:N
d(1,i)=input('Distance = ');
end
d
This will prompt you three times to give a distance value - and after the loop, d will come out as 1x3 vector with elements being the input values you used.

You're right. No clue why my functions not doing that and unfortunately I'm not able to give the code. Thanks for trying though.
Can you think of any reason why it's not working?
Edit: Is there a way to run a function line by line like a live script?

Note that there is no reason you need to do this with a loop. A vector can be entered with a single input statement, e.g.,
>> d=input("Distances = ")
Distances = [1,2,5,7]
d =
1 2 5 7

Yes, I'm aware. However, this is not the only case for which I'm using this method. Anyway, I realized my error and it's fixed.
Thank you though

Yes, the Debugger.
