I'm using WP 3.3 and GF 1.6.2
I would like my Opening date and Closing Date on same line with Closing on the right.
I see the documentation and go to Edit Field/ Advanced/ CSS Class Name and enter: gf_left_half for Opening Date and hit Close in Blue tab
Then I go to Closing Date and under Advanced/ CSS Class Name enter: gf_right_half and close blue top tab.
The Documentation says to, "Save it." I don't see where to save it. So I hit Update Form and sure enough, it does not get saved.
