I am trying to figure out what statement(s) are failing with this model... the compiler is complaining about some real numbers being larger than 64 bits, but there are no "real" variables defined in the model. Could possibly be related to a "time" variable or net delay (such as #tPUW).

Any brief analysis or suggestions would be greatly appreciated.

Thanks! ;-}>

Here is the compile listing:
