Subscriptions: Can day range include final days of the Month?

Hello,

When I established a Data-Driven Subscription for the report to run during the Month for the days: 24-30,

I gain this error:

The value provided for the StartDateTime field is not valid for its type. It
cannot be converted from a string value to the type that is required.
(rsElementTypeMismatch)

I can establish the Subscription, if I select a day range of 1-5.

I need this report to run at the end of each month. The day range is the final two business days of the month.

Is the error explaining that not all months include a 30th day? Therefore, cannot be established?

If this is the case, is there a workaround to help?

Thank you!

Mark
