We need to create a form asking the clients for their age. Is there any way to create a field where you can only fill in numbers - maybe only 4 numbers like 1976 or 2011?
Another field input would be date. It would be perfect if I could limit the number - something like "not lower than 1800 and not higher than 2012" to prevent invalid numbers.
I can create a question with drop down list, but creating a list of all possible years would be stupid and uncomfortable to choose from.
