Praveen, On thinking about your problem a little more, I now understand the issue with needing 12 different templates. However, there may be a solution using the #set global command, and then using #include.
Briefly, it would look something like this: #for i in range(1,13 # set global month=$i # include "Climatology.txt" #end for Then the file "Climatology.txt" would be very similar to what you have, except it would be parameterized by the variable $month.
