Nintex Form 2013 inline function 'lessThanOrEqual' and 'greaterThanOrEqual' are not working for the date value comparison.
When using inline function 'lessThanOrEqual' and 'greaterThanOrEqual' to compare a date value, the function is not returning the expected result.
This is a known issue that has been fixed in the latest version of Nintex Form 2013. Update the Nintex Form 2013 with the latest version or at least the one that released by July 2018.
lessThanOrEqual(date, current date) The inline function should ensure that the date field of a form should only accept date value that is less than the current date. As the result is doing the opposite.
