How do I call upon a function in another function?

This is what I have:

function [Output] = Jamiesonlab5 ()
Result=input('Please press any key to roll the dice, press Q or q to quit program: ', 's');
if (Result == 'q' || Result == 'Q')
    fprintf('program terminated')
else
    X=rdmInt();
end
Output=getPhrase();
end

function [TextI] = num2txt (I)
if I==1
    TextI='one';
elseif I == 2
    TextI = 'two';
elseif I == 3
    TextI = 'three';
elseif I == 4
    TextI = 'four';
elseif I == 5
    TextI = 'five';
else
    TextI = 'six';
end
end

function [i] = rdmInt ()
Max=input('Max: ');
Min=input('Min: ');
x=rand();
d = x * (Max-Min+1);
e=floor(d);
i= d + Min;
end

function [] = getPhrase ()
x=rdmInt();
fileID = fopen( 'OUTPUTLAB5.txt', 'a+');
if x == 1
    fprintf(fileID,'Congragulations!');
elseif x == 2
    fprintf(fileID,'Way to go!');
elseif x == 3
    fprintf(fileID,'Youre amazing!');
elseif x == 4
    fprintf(fileID,'Fantastic!');
else
    fprintf(fileID,'Wow!');
end
end

Essentially what I want to do, is get a number between 1 nd six, and output a message corresponding to that number from my first function. However, it claims I have too many output arguments at the top. Also ignore the num2text fumction, it hs no importance to my question.

You request an output from getPhase() here,

Output=getPhrase();

but your implementation of getPhrase() does not return any output

function [] = getPhrase ()
