"[other]" Species Trap

[stdavis]

• When you chose "[other]" in the "Species Code" drop down, you get stuck in an endless loop and can't choose another species. It also incorrectly shows "[other]" as the value rather than the new code that you entered.

A few other enhancements:

• Prevent users from overwriting existing codes (don't let them input a new code or description that already exists in the list).
• Sort the list in the other dialog by description.
