Populating Listbox in a Userform with a named range from another sheet

Hello All and thank you for any help you may be able to offer in advance. The code I've placed below is called from a macro on a different sheet (Framing Tool) and is meant to first determine the size of a list, make that list into a range, and then place the range as the options in a listbox. However the code is creating the range from the current sheet rather than WsOppDB and I cannot figure out why, any thoughts?

Also, I'm having trouble understanding the difference between .list and .rowsource.
