Trouble Matching Data in Indexed Array

Hey, everyone! I'm trying to create a program where the Array "Accepted" has a direct correlation to the Array "Values". For example "A" would be given value "1", "B", "2", and so on. and then at the end it asks how many units of the variable of "Accepted" and divides it by its given value. So if I said 7 units of "C" it would return "7/3 total C". So i created these arrays but i don't know how i would link them up that way. the way I have it I feel that it would just take the entire array rather than assigning each array a specific value of the other. ideas?
thanks!
Accepted = {'A','B', 'C'};
Values = {'1','2','3'} ;
letter = input('what letter? ','s');
if any(strcmpi(elmnt,Accepted))
disp ('\n')
else
disp ('that''s not going to work')
end
units = input ('how many units of it?');
fprintf('%d units of (Accepted)', units/(Values))

You can get the index of the matched item easily:
index = find(strcmpi(elmnt,Accepted));
I find disp, and concatenation easier to handle than fprintf
disp([num2str(units) '/' Values{index} ' of "' elmnt{index} '".'])

You're not using {} [braces] and () [parentheses] correctly.

i know, i know, but when i keep the braces i get.
"??? Cell contents reference from a
non-cell array object."
Error in ==> thing1 at 12
disp([num2str(units) '/'
Values{index} ' of "' elmnt{index}
'".'])
and then i'm lost. but i do appreciate all your input
