You may want to review these two pages from Debra Dalgleish's site:
http://www.contextures.com/xlUserForm01.html
and
http://www.contextures.com/xlUserForm02.html

And another option from John Walkenbach's site:
http://j-walk.com/ss/dataform/index.htm

The features say you can use dropdowns.

And the source code is available for a small fee ($20 USA, IIRC).

I'm attempting to create a program that will allow a user to select inputs
from a multiple combobox userform. Those inputs will then populate a list in
to which the user can add dates, creating a schedule. This is a lot like MS
Project but I want to add a few additional things to allow us to break out
costs per phase of a program, by type of labor, by year, by quarter. This is
what the boss wants too. Getting these taks done would really help me get
started.

Thanks
