Here is the scenerio,

I have a number like this 30-015-00745 in cells A2 to A150. The
important part of that number is the 3 middle digits. Example: 015

I have another page that lists several hundred 3 digit combinations.
Example: 015

How can I validate that the 3 middle numbers exist in the list on page
2 where I store all the possible 3 digit combinations that are
allowed?

I have created a named range for the 3 digit numbers on page 2 because
I know the built in validator doesn't like going to a different page
to get a list to validate against. So I created a name range called
"validlist".

Is it possible to perform this validation on the three digits in the
middle of the string 30-015-00745 and if so how might I go about
doing that validation?
