Why is my while loop infinite?

I'm not sure why this loop is running infinitely; shouldn't it end as soon as nVal is equal to the value of inputM?:
clear;
clc;
inpuTm = input('Enter the value for m: ');
nVal = 2;
pofN = [0,1];
while nVal <= inpuTm
pNext = 2*(nVal-1)+(nVal-2);
pofN = [pofN,pNext];
end
disp(pofN);

Yes, but neither nVal nor inpuTm are modified inside the while loop, so they remain unchanged and the loop either never executes or is an infinite loop depending upon the value of inpuTm.

nVal should increase by 1 until it equals the 'inpuTm' to create a vector 'pofN' with nVal number of values.
