Re: fatal:Undefined identifier: (rainfall_tot) is undefined, can't continue

The error is telling you exactly what the problem is. You are trying to reference the variable "rainfall_tot" which doesn't exist.

The error is on this line:

> prcDay(nt/24,:,:) = dim_sum_n(rainfall_tot(ntStrt:ntLast,:,:), 0)

Perhaps you meant to use "rainfall_hour" here instead?
