Need help with error code

I am getting this error code:

Unrecognized function or variable 'UI_input_table'

When I try to run the first line of my script:

clear;
[T,file_name]=UI_input_table();

The exact same codes works on my colleagues matlab program

Not you assist me in figuring why I am getting this error code and what it means?

Most likely, your colleagues have this function program file stored in one of the folders on their computers.

function [T, file_name] = UI_input_table()
    % code
end

UI_input_table is not a Mathworks supplied function, so it needs to be defined by a .m or .mlx file somewhere on the MATLAB path.
