By the way: your age calculation fails if I was born in 1901.
I knew you were a pensioner, but I didn't expect that...
How high are the chances that someone born in 1901 is still alive, using this online questionnaire and requiring and MRI? I think one can risk it not to work from 1901 downwards. Hahahaha.
I answer at the LimeSurvey forum in my spare time, I'm not a LimeSurvey GmbH employee.

No, I was thinking about setting a realistic minimum year.
You can set this by
"minimum date": "-75 years"
"maximum date": "now"
Now the drop down starts at 1900 and while testing I clicked something there.
But it's an interesting fact that I will investigate.
In that case the difference (time - mktime) exceeds the size of an integer (4294967295)
But I have the idea why the equation failed.
Here (age>11 and age<50) or (age>49 and (QMenopause=="Y" and QMenopauseYear=="N")) or (age>49 and QMenopause=="N")
QMenopauseYear is not defined, if
QMenopause=="N"
age<50
So the whole equation will not work.
Therefore there is the NAOK.
