Setting separate validation on multiple numerical input fields - by: andogro

Hello

I am trying to setup a survey with multiple numeric fields that have limited answers for example:

Height Feet: (limit to 2-7)
Inches: (limit to 1-12)

and birthdate Month: (limit 1-12_
Day: (limit 1-31)
Year: (limit to a particular age range of our subjects)

I don't want to put these in separate questions as it becomes rather clunky. I think this can be done with the EM but not sure where I enter the values. I am using limesurvey 2.00

Thanks!
