I am trying to do validation on multiple fields with the custom validator in ASP.net using JQuery but I can't get it to work.There is a drop down box which contains two values, based on these values other items appear.So if the user selects option 1, then a text box appears, if they select option 2 the text box disappears and two drop down boxes appear.Depending on what option they choose I want to validate their input.What I have so far that is not working is.ASPX\[code\]<asp
