I have a Userform with 2 Comboboxes on that should get the data ranges from an external workbook. I'm stepping through the code with F8 to see the process, everything runs without errors but the ComboBoxes are empty when the userform shows.
The named ranges are set when I check it in the Watch window. I'm not sure if the problem comes in with the userform_initialize when I assign the named ranges to the combo boxes?
Any suggestions will be appreciated.
