"Error at on update script"

"Error at on update script"

I made a couple of changes to my form, and now I can't update an existing record, because when I do:

Error at on update script.

Note: We are working on giving more meaningful error messages on script failures

All I am doing is changing one text field, so it's not like I'm acting on the world, here.

I removed all onUpdate scripts from the fields, to no avail and no change in the error.

The only things I've changed since yesterday:

* I made a field a numeric field.
* I added add-validation on that field.

I have shared the application with Support.  It's the Companies form.  Thanks.

(If you want to test, try changing, in a company name, the & to an 'and', or vice versa.  V easy.)
