Patrick,

There are a couple of things to check with your variable definitions:

GDATTIM for model forecasts should be formatted as 1200F000 (for example)

GDPFUN contains an extra left parentheses, and should be

GDPFUN = SUB(LYR_MXMN(TMPC & MXOUT & HGHT|1000-100),HGHT@0%NONE)

These two edits work on my end.
