Again, I'm not sure what I'm doing that is causing this error. I've tried a few variations in configuring the model, as well as using InitialiseTo() on the variable array (rnaEndLevel) that appears to be causing the problem, but to no avail.
Please let me know if you have any suggestions. Thanks,
Ravi
