I have a dropdown field called 'Type' which has 3 choices lets say A, B and C.. I then have a dropdown field next to it called 'Choices' that has 15 choices lets say they numbers 1 to 15. If I select 'Type' A I only want to see numbers 1 to 5, if I select B I only want to see numbers 6 to 10 and if I select C numbers 11 to 15. How would I set this up and does this have some kind of name? Dependent list??
