Hoi all,

I have 2 date questions startDate and stopDate.
I want to limit the stopDate with date_min=startDate and date_max=now.

In the date_min field of stopDate, I entered stopDate, which did not work for me so I followed the solution proposed here: www.limesurvey.org/en/forum/can-i-do-thi...-using-date-of-birth

I enter the following expression:
{date("Y-m-d H:i",mktime(0,0,0,intval(substr(startDate,5,2)),intval(substr(startDate,8,2)),intval(substr(startDate,0,4))))}

This does not work, I always see 1999 as the minimum date when I test.
I've attached a simple question group with startDate, stopDate and a boilerplate question displaying all variables.

I use version 2.06+ build 141210
Any hint is appreciated.
