2 combo boxes 2nd dependant on first (with conditions)

[brentcook]

First, you guys are awesome and have been so helpful. I find myself in another quandry.

I have a table on another sheet in a workbook that contains a dynamic table connected to a sharepoint contacts list that has School, Counselor, Email, Fax, and Phone.

Currently I use data validation to find the school from a list, then the counselor list is dependant on the school selected and lists only the counselors for that particular school, then autofills the 3 last boxes based on counselor.

I would like to use comboboxes because of the autofill tool that isn't available in data validation which would speed things up and ease the process considerably.

I have tried multiple ways and can't even get close so I scraped it.

My questions are: can I have data validation use a formula that is based off of the input of a combobox? If so, it would be an easy fix. The formula I have in the "Counselor" data validation is:

=OFFSET(Contacts!$A$2,MATCH($U$4,School,0)-1,1,COUNTIF(School,$U$4),1)

U4 is the School Input

If not, does anyone have an idea of code for the combobox of counselors to get me headed in the right direction?

Thanks again for all of you. You have saved my butt so many times.
