Hi Conny,
Are you placing the text fields in a layout or just declaring them as
provided below. If you are not using a layout enclose these TextViews with
in a Layout and try. I guess it should work.
Also try refreshing R.java & build you subset.xml
Check if the price variable is reflected in your R.java file.
Thanks & Regards,
Yousuf Syed
