Sorry, it appears in a Control File where I've used templating, and set the 
time to pick up the file for 1jun2013. Then it complains. If I don't use the 
templating, as in the previous Control File where the file name is fixed, it 
actually does work for multiple variable display/reads. Here is the control 
file with templating (you'll have to rename the .he5 file however):
