so code ...i applying alpha numeric validation on 2 field problem if give first input field valid input , second invalid form submitted doing wrong? ...i new web appreciated:)

updated answer:

fine! different =)

one line, should validate both fields regardless if validate_course_name() returns false.

jsfiddle:
http://jsfiddle.net/fvqty/3/

function validate() {     return (validate_course_name() * validate_course_desc()) == true; }

let false = 0, true = 1. math :)
