HAVING TROUBLE WITH PLOTTTING

Can someone help me with my code because it says error in plotlump here is the code
FOR LUMPSUM.M
while(1)
[val,Principal,Number,Interest] = inputvalues;
if(val(1) == 0)
disp('Entered Principal Amount is wrong ');
disp('Please enter the details again ');
end
if(val(2) == 0)
disp('Entered Number of years is wrong ');
disp('Please enter the details again ');
end
if(val(3) == 0)
disp('Entered Rate of Interest is wrong ');
disp('Please enter the details again ');
end
if(sum(val) == 3)
break;
end
end
% function call to plotlump function
plotlump(Principal,Number,Interest);
FOR INOUTVALUES.M
function [e,P,N,i] = inputvalues
% Taking input from the user
P = input('Enter the Prinicipal Amount Invested : ');
N = input('Enter number of years : ');
i = input('Enter the rate of interest : ');
% Then this checks if there is an error
e = errorcheck(P,N,i);
end
FOR ERRORCHECK.M
function value = errorcheck(Principal,Number,Interest)
% If they are valid , then value holds as 1 meaning they are valid while
% value holds 0 meaning they are wrong
value = [1,1,1];
if(Principal <= 0)
value(1) = 0;
end
if(Number <= 0)
value(2) = 0;
end
if(or(Interest < 0,Interest > 100))
value(3) = 0;
end
end
FOR PLOTLUMP.M
function plotlump(Principal,Number,Interest)
% This loop will calculate value of S
S = zeros(1,Number);
for N = 1:Number
S(N) = (Principal * (1 + (Interest/100))^N);
end
Im having trouble with plotlump because everytime I enter the code it's saying "Not enough input arguments.
Error in plotlump (line 6)
S = zeros(1,Number);"

Have you removed something from your plotlump code? S = zeros(1,Number) is not on line 6.
When I put this all together, it runs without error for me. I've simplified the code to run here.
while(1)
val=[1 1 1];
Principal=1000;
Number = 1;
Interest=6.5;
% [val,Principal,Number,Interest] = inputvalues;
if(val(1) == 0)
disp('Entered Principal Amount is wrong ');
disp('Please enter the details again ');
end
if(val(2) == 0)
disp('Entered Number of years is wrong ');
disp('Please enter the details again ');
end
if(val(3) == 0)
disp('Entered Rate of Interest is wrong ');
disp('Please enter the details again ');
end
if(sum(val) == 3)
break;
end
end
% function call to plotlump function
plotlump(Principal,Number,Interest)
function plotlump(Principal,Number,Interest)
% This loop will calculate value of S
S = zeros(1,Number);
for N = 1:Number
S(N) = (Principal * (1 + (Interest/100))^N)
end
end

% Here is a slightly edited/fixed version that works ok.
while(1)
[val,Principal,Number,Interest] = inputvalues;
if(val(1) == 0)
disp('Entered Principal Amount is wrong ');
disp('Please enter the details again ');
end
if(val(2) == 0)
disp('Entered Number of years is wrong ');
disp('Please enter the details again ');
end
if(val(3) == 0)
disp('Entered Rate of Interest is wrong ');
disp('Please enter the details again ');
end
if(sum(val) == 3)
break;
end
end
% function call to plotlump function
S=plotlump(Principal,Number,Interest);
function [e,P,N,i] = inputvalues
% Taking input from the user
P = input('Enter the Prinicipal Amount Invested : ');
N = input('Enter number of years : ');
i = input('Enter the rate of interest : ');
% Then this checks if there is an error
e = errorcheck(P,N,i);
end
function value = errorcheck(Principal,Number,Interest)
% If they are valid , then value holds as 1 meaning they are valid while
% value holds 0 meaning they are wrong
value = [1,1,1];
if(Principal <= 0)
value(1) = 0;
end
if(Number <= 0)
value(2) = 0;
end
if(or(Interest < 0,Interest > 100))
value(3) = 0;
end
end
function S =plotlump(Principal,Number,Interest)
% This loop will calculate value of S
S = zeros(1,Number);
for N = 1:Number
S(N) = (Principal * (1 + (Interest/100))^N);
end
end

I guess my point was that I didn't have to edit anything in the code the OP shared for it to work. I only modified it so it could run in Answers and produce an ouput, showing that I am not able to reproduce the input argument error to plotlump.
