[Paraview] loading time variant data via a script file

[John Vines <jvines>]

All,
	I am trying to load time variant, multi-block Plot3D data via a .pvs
script and am not having much luck.  I have 12 grids and 40 timesteps
for each grid.  The script will load only the first timestep.  Will
a .pvs file load more than one timestep?  Am I doing something wrong?  

I am using Paraview 2.5.

Thanks in advance,
John
