Thanks Linda. Turning off this flag allowed the program to run. I assume we (users) cannot do anything to allow the evapotraspiration model to work.
Also, is the "\obsolete=>EquivalentSlab" a bogus message? Anything we should be concerned about?
Thanks again.
Homero.

- First, when I try to open the IDF in the EP Launch, it shows an "Invalid Slash Codes Found" window. The message says:
