Hello, i'm working on a website and i have 4 dropdown's that are on a page and i want to make them dependent. Right now i have them set to pull from the database but i want it set to based on what they select on number 1 it populates number 2 and number 2 populates 3 and 3 does 4 and so on. Can someone take a look at my code and help me to achieve this as i have never done it before and would appreciate any help at all..
