conform?

Hi all£¬
 
I write a simple script(atteched) with "clmMonTLL"and "conform" function to calculate the grid difference with a long term monthly means.Though, I obatin an error following that I cannot solve even if conceptually very simple.Can any body help please?
 
Thanks in advance!
 
Regards,
sunflower
