16. Have the Day slider selector be set to more than 5 months.

CAUSE:
 
This is a known in Strategy 9.3 where very long URL strings that are past a browser's limitations when passing prompt answers through URL API. This issue has been logged to technology.
 
ACTION:
Strategy will continue to investigate and post updates as soon as they are available.
 
WORKAROUND:
1.Have users select smaller number of selections.
2.Implement a third-party URL shortener to shorten the URL string such as goo.gl.
3.Append the web.config file within \MicroStrategy\Web ASPx to increase the value of maxQueryString="length".
NOTE: This workaround does not apply to Internet Explorer browsers because they have a set URL string limit.
