Indirect in userform combo boxes

[bwestfall]

While in a worksheet using two drop-down lists referencing several named ranges on a separate worksheet, I have used the Indirect function to drop down certain cell references in a drop down list depending on the value selected in the first drop down list. However, when using a Userform I'd like to do the same thing. Can anyone give an idea how I might go about this?

It's called cascading comboboxes. In the change event of the first CBox, you have the ability to run additional code to fill/select/etc the other combobox.

But without an example worksheet with the userform, I'm unable to be more specific.
