Not able to open fis editor file

I saved a file fis editor. When I type "Fuzzy filename". File name is fuzzytest.fis. It does not open. Istead it gives an error

"Error using fuzzy.internal.utility.getStringIfErrorIsNotThrown" 
"Error in readfis (line 52)
    errorStr = fuzzy.internal.utility.getStringIfErrorIsNotThrown(throwError, ...

Error in fuzzy (line 42)
        fis=readfis(action); "

To confirm: you are doing

fuzzy fuzzytest.fis

not

filename = 'fuzzytest.fis';
fuzzy filename

? The second of those would attempt to open a file named 'filename', and would be corrected by

fuzzy(filename)

You have to change the current active folder to the path where your m-file is located. this way it will run without this error.
