More detail might help. Are these custom values value lists or "use values from field" value lists? If the latter, what other options, if any were specified?
These are custom values. Because of other factors, the field had to start out with zero. I figured it out, though. Users needed to choose a value from 1 to 10. When run locally or directly from the server, it ran fine. When run from the web, I had to include the zero in the drop-down list even though that shouldn't be a choice. All set now.
