Nancy,

Are the "date" fields in the back end data datetime instead of Date?

Use {/:} for an empty datetime field.

This has worked for everything except the date fields. I still get a 1526 error (data type mismatch is the text). All other data is updated... and the dates are left blank, but the error occurs... not something I want users to deal with.
