Help Needed with Multiple Dependent Comboboxes in Userform

Anyone out there have any idea on this? I still am stuck. I have Advanced filter working mostly, but am having issues with the ComboBoxes only showing parts of the lists and faulting.  I can enter filter criteria with no problems on the Filter sheet, but when I do it from the Combo boxes, I get faults.  Maybe a circular reference?
To much detail to be able to explain it in detail.  I have uploaded the file.  It consists of one Userform with many dropdown boxes.  First choose the Platform, then choose the Division or Chamber Description.  It presently faults and I cannot determine why.  There are 10 rows of dependent combo-boxes and they use the same data to feed each set.  The Filter sheet seems to work well, but I can't get the Combo boxes to match up.  

Would love to see if anyone can figure this out.  Have watched many YouTube videos, but they all do not go into enough detail for this.

Thanks
