My functin wont run my if statement. How do I fix this?

function [ PrimeF ] = Question_4( X )

clear all

clc

prompt=('Please enter a 2 digit number');

Inp = input(prompt);

X= Inp

if X >= 100 && X < 10

    fprintf('That is wrong, please enter a positive 2 digit number')

    if X <=99 && X >=10

        PrimeF= factor(X)

    end

end

How can x by greater than or equal to 100 and less than 10? It can't.

Perhaps you meant or || instead of and &&, or maybe you want to flip the comparators <= && >
