If there is a field called "max_age" on the form, but the user leaves it blank, you won't get nil from params, you'll get an empty string. So if you check for max_age.blank? instead, you should get the result you want. (Running a debugger would help you find this out very easily, or even just outputting the value of max_age to the console to see if it's what you expect it to be...) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
