Why am I getting a parse error?

I am getting a parse error at the h variable for a basic HW problem.

h = input('Please input the water height.');
if  h >= 0 && h <= 40
    vcone = pi*10^2*15;
    r = sqrt((2*(25/2))-(h^2));
    vsphere = ((h*pi)/6)*((3*r^2)+(h^2));
    vtot = vcone + vsphere;
    disp(vtot)
else 
    disp('The water height was invalid')
end

Please post the complete error message text, along with the offending line. I can only guess that maybe you have a variable named "input" that is shadowing the MATLAB "input" function.

I closed and restarted the program, and now there is no error. I'm not sure what it could have been.

[James Tursa]

It was probably exactly what I stated ... that you had a variable called "input" that was shadowing the MATLAB "input" function. When you closed and restarted MATLAB, that cleared that "input" variable. You could have also manually cleared the "input" variable to fix this.

Learning Opportunity: Don't name variables the same as important MATLAB functions, like "input" or "sum" etc.
