You need to be very careful, you cannot have any non-VSS references in the sketcher (certain rare cases exempted), and you cannot use any dimensions that will lock geometry unless you REALLY want it locked. That dimension you had in the section FUBAR'd it. Also, VSS's are sometimes very finicky, and the best thing to do then is delete the feature, and start over again using the curves you want and sketch a new section.
I fixed it and simplified it a little, but you might want to check the height. The height should ONLY be controlled by the top curve with the conic. I also replaced the arcs in the obround sketch with conics.
Have fun with it!
