I am writing a script that would validate a statement. The tasl is to promt the user for the values specified below. For each value entered by the user, use a while loop to validate each value according to below. The statement I am trying to validate is "Number of Subintervals" and the value has to be greater than 1. N>1 where N=subintervals.
This is what I got and it does not work.
N=input('enter a number of subintervals greather than one')
while N>1
if N<1
disp('Please enter a number greater than 1')
end
end
If there is anyway you could help that would be great as I am new to coding.

If the user enters a number less than one, they should be prompted with a statement to enter a number greater than one. If the user enters a number greater than one, it should leave the loop to continue on to another statement validation.

I think your while loop needs to have the input() within it
While the user hasn't given a valid number
Ask for a number
if the number is good, leave the loop
else offer a suggestion
end while
