The number you input should be within the min-max range, otherwise
xcrysden will complain. 

Note also that when you input the isovalue number, you should
mouse-click the "Submit" button (it is located at the bottom right of
the "Isosurface control" window). Only then xcrysden will calculate the
isosurface.
