when entering the expression
"If(PrevTSValue(Snow Depth[m])=0, Albedo Lower Bound,
PrevTSValue(Snow Depth[m],1)>PrevTSValue(Snow Depth[m],2),
why is always appear "Expression refers to an invalid branch/variable combination"?
I have WEAP version 2017.

I am not sure why you are getting an error for that expression. I just tried it and had no problem.
I strongly encourage you to install the latest version of WEAP (2018.01). It has many new features and several bugs have been fixed. It might help your problem.
