This can be achieved with a different approach:
To do this I used a dual axis and overlay the bars and changed the size of the Actual Hours bar. Then all you need to do is show the mark labels. See the attached workbook.
Also make sure you synchronize your axes and then hide one of the headers! You might also want to edit your axis name like I did
Thanks so much for the quick reply, that's exactly what I needed, thanks!
Happy to help!
