Hello,

I am afraid your copying-and-pasting an error message into the Discussion Forum without providing any context makes it unlikely that you'll get useful responses, if any. You will be more likely to induce responses if you can describe what you are trying to model (especially if you can do so in mathematical terms) and attach your .mph file.

Best,

Jeff
