What is wrong with my coding?

Enter the magnitude and the position of the loading factors lateral to the beam axis, including point loads, moments and uniformly distributed loads. The number of the loading factors of the each kind must be defined by a user interactively. The input data control must be implemented.

% Get the value of the point load acting on the beam along with its positions
npl = input('Enter the number of point loads acting on the beam');
n=0

while((n < npl))
    p(n+1) =input('Enter the point load')
    loc(n+1) = input('Enter the distance of point load from left end')
    
    % Check if the point loads are present inside the beam
    if (loc(n+1)>l)
        sprintf(' The point load cannot be outside the span of beam')
        loc(n+1) = input('Enter the distance of point load from left end')

    n = n+1
