Hi Jim ,
I think what you mean by comments are not what Excel means by comments.
If you say that you have made a comments table with numbers , I assume you mean that you have a lookup table , where you have numbers down one column , and in another column , corresponding to each number , you have some description.
If all the numbers in the numbers column are unique , then given any number , we can retrieve the corresponding description.
Is this what you want ?
If so , it is very simple to use either the VLOOKUP function or a combination of the INDEX and MATCH functions to get this.
