Comment 4 for bug 1731010

Update to this bug with a little clarification.

The subscription will fail to save if the date is blank or NOT in the date format defined by the library setting for "Deprecated:Format Dates with this pattern".

We updated the Format Dates settings to MM-dd-yyyy, and the subscription now needs the date in this format.

There should definitely be some form of visual indication why the subscription fails to save, (i.e. the date box could become yellow similar to date fields in Patron Registration).
