Vertical Separator Bar in Custom Ribbon

[odyssey]

Can somebody tell me how you insert a vertical separator in a custom defined ribbon? I have several text buttons calling various macros and I want the layout to be along the lines of 3 rows of buttons in a column, then the separator, then the next three buttons, the separator etc, but all within the same group.

Thanks for any help!

Finally figured it out! Simply had to use the command:

<separator id="sep"/>
