Hi,
Sorry about the thread name, accidentally hit enter. Is there a way to edit that?

I'm attempting to save data fields in a form and it appears that when one field is emptied, none of the fields save properly.

Specifically the Rim Elevation field. When that is deleted by the user, all the other fields are deleted as well, but the feature still exists.
I've highlighted where I'm guessing the problem area is. Also, I apologize, the code sloppy as it's being written and edited by 3 different people.

Fixed the issue. I needed to call my CheckNullString method on the field instead of CheckNullNumber.

By the way, you can change a thread title by hitting Edit Post and then Go Advanced, although I think you can't do this once there is a reply.
