Reynolds number, FalsePosition getting multiple errors with no output

I am to create a function that uses FalsePosition (function shown below) to solve for f in the given equation. I think I'm missing some connections between my script and the function I'm trying to call.

Here is FalsePosition

This is my code:

function [root, fx, ea, iter] = falsepositionnew(y)
xl = 2500;
xu = 1000000;
es = 0.0000001;
maxit = 200;
Re = 10000:200000;
y = @(f, Re) 1/sqrt(f) - 4*log(Re*sqrt(f))+0.4;  %equation given 
for = i:numel(Re)
    f(i) = falseposition(y,xl,xu,es,maxit);
end

%if true
for i = 1:numel(Re) % change this line

[VBBV]

%f true
FalsePosition(y,xl,xu,es,maxit)

Function name is case sensitive

What needs to be changed about the for line?

Notice the change in case for the function name in your code in for loop. And the name on the code snaphot you showed.

The function also outputs more variables than what its shown in for loop.
