Combobox with dynamic data validation not working!

Hello folks.

I've been trying to use the combobox trick (found on the Contextures website) to get a dropdown list convert to a combobox upon doubleclick (so I can get tweakable font settings, so the font in the drop down list isn't tiny when the page is zoomed out).

I can get it to work perfectly when the data being populated into the list is a named range of a specific static set of cells (eg, named range STAFF set to cells A2:A50 on sheet 'Staff_List"). However, I'm using a dynamic named range (where the range to show in the list changes depending upon the value in the cell in the first column).

The code is below. I have some msgbox's in it to help with checking the code. The first half of the IF statement checks to see if the cell that contains a name of a staff member has been double clicked, and if so loads the list of names from the STAFF named range on the 'staff_list' worksheet. This part works just fine - loads the list properly in the combobox that replaces the standard dropdown.

To test the second half I'm just trying to get it to work in one cell to start with (c5). The data validation works fine on this cell if I single click - the source is set to a named range (=TypeChoice), which I defined in the name manager as a long nested conditional that references several other named ranges (NC2, LEAVE2, etc) located within some hidden rows on the primary worksheet, Sheet1. So, the data validation source for the cell is "=TypeChoice", and TypeChoice is defined as:

=IF(Sheet1!$A5="NC",NC2,IF(Sheet1!$A5="LEAVE",LEAVE2,IF(LEFT(Sheet1!$A5,1)="1",TYPE1,IF(LEFT(Sheet1!$A5,1)="2",TYPE2,IF(LEFT(Sheet1!$A5,1)="3",TYPE3,"neither")))))

When cell C5 is double clicked, my msgbox tells me that the str variable has properly been set to "TypeChoice" (in the same way the msgbox under the 1st half of the IF statement tells me the str variable is set to STAFF), but the combobox contains nothing (just a single blank value). I don't know if its because the TypeChoice list is dynamic and not a very specific single range (like the STAFF case)>

I'm hoping someone can help out!

Thanks in advance,
Corman

Excel Facts

How to create a cell-sized chart?
Tiny charts, called Sparklines, were added to Excel 2010. Look for Sparklines on the Insert tab.
No ideas? Anything would be appreciated!

Thanks!
