VB Run-time error '9'; Subscript out of range

Hello everyone:

First I want to say that the Recursion1.xls file that I downloaded from this site is a marvelous thing.

Next I want to say that my parade was rained on earlier when I went to enter a list of 169 values and it came back with the above titled error.

I realize that increasing the range will cause the program to run even longer, but the need far outweighs the wait, believe me!

If anyone can explain to me in laymans terms how to increase the range to include a list of 169 entries or more, I would appreciate it. Attached is the current recursion file that I am working with.

I hope that someone can help me soon. I will be indebted to you forever, really!!

Thank you in advance!

Lisa
